Studiologic Numa GT review

REVIEW – Studiologic Numa X Piano GT | 2024 Stage & Studio Digital Piano | $1999 internet price – This new Studiologic stage piano model is called the Numa X Piano GT. After playing it for many days and hours I can say that I am very impressed with what it can do and how it plays as a piano along with its vast array of quality internal non-piano instrumental sounds and effects.

Numa X Piano GT user interface controlsIf you are a pro keyboard or stage digital piano player and/or you work in a recording studio then you likely know the name “Studiologic.” But…if you are a amateur musician playing at home, church, school, or at small individual gigs, or you are a piano student or acoustic piano player, then you may not have heard of this brand before.
This is because Studiologic has been primarily known for designing and producing “controller” keyboards and stage pianos as well as MIDI controllers for other music products. They do not design and build “home digital pianos” or home keyboards for general purpose music since they typically focus on the pro musicians. But that does not mean you cannot use a few of their models for home use, especially with this new Numa X Piano GT. 
In this detailed review of the Studiologic Numa X Piano GT you will learn about the good & the bad of this top-of-the-line stage & studio digital piano which will help you decide if this new model is right for you.


Studiologic logo
Studiologic is actually an Italian brand of stage digital piano and MIDI controllers that is part of the Fatar company of Italy. The Fatar company started 67 years ago in 1956 so they have definitely been around a long time. The Fatar company is especially known for designing and producing professional key actions for a variety of keyboard instruments. 
Fatar logoIt is well known by music industry people that Fatar builds key actions for other digital piano & keyboard brands such as Nord, Kurzweil, and Dexibell, among others. The Fatar company has their own keyboard/digital piano brand called “Studiologic” which they began producing in 1986. So whenever you see a Studiologic instrument, it is really from the Fatar company of Italy.
Fatar also designs and produces their own proprietary digital electronics, user interfaces, and connectivity hardware for all their own products, so they are a very well rounded and experienced company. Also, when it comes to the Studiologic brand, Fatar will typically put their best key actions in their own brand as opposed to the other keyboard brands that use Fatar key actions. This is the case with this new Studiologic Numa X Piano GT which is using their best piano key action.


I really didn’t know what to expect when I first sat down to play this XGT instrument because I don’t normally focus on pro stage & studio brands & models. I certainly have had experience with them and have played many of them professionally for many years, including Studiologic. However, I generally focus on portable and cabinet digital pianos that have their own internal speakers in them, and stage pianos traditionally do not have internal speakers, and the Studiologic Numa X Piano GT is no exception. 
KRK studio monitorsBut since I have high quality studio monitors/speakers in my teaching & recording studio, then that’s not an issue for me. Plus, I always test out these digital pianos with good stereo headphones as well. My primary purpose in trying out this newer model is that I have been hearing some very good things about it in its lower price range of under $2000. I personally wanted to see if it could actually come close to reproducing a solid and more realistic piano playing experience which is important to me, along with the other instrumental sounds that it offers.
If a digital piano can excel in a very positive way when it comes to playing “piano” and having a great experience that way, then the rest of what it does is just “frosting on the cake” to me. If the piano playing experience is impressive and that “frosting on the cake” for all the other things it does is equally super tasty, then that’s when I can say that digital piano is a winner. So the question is…is the “Studiologic Numa X Piano GT” a winner? 


XGT full size top view
Before I answer that question…I think the name of this piano is way too long (Studiologic “Numa X Piano GT”) and a bit confusing to some people. Perhaps Studiologic company has their reasons, but it doesn’t work for me. They do have another model called the “Numa X Piano 88” which is the same piano as the GT version but with the exception of the key action. Both models have 88 keys so even the amount of keys are the same. 
The “88” model has an entirely different key action mechanism and it does not feel like an acoustic piano key action. It has the same digital technology and digital features as the Numa X Piano GT, but it’s the key-action where the big difference lies. So I don’t recommend it (the 88) as compared to the XGT if you want to be sure you get a more realistic piano key action response.
Fatar Grand Touch key actionThis new top-of-the-line model has the letters “GT” added to signify this one has the new Studiologic “GrandTouch” TP/400 Wood key action. This specific GrandTouch key action is far superior to and completely different than the other Studiologic model Numa X Piano 88 and any other Fatar models with the GrandTouch name or logo. Fatar/Studiologic uses this generic “GrandTouch” name, but the actual key action is called TP/400 Wood and that’s the most important part of the key action name. I will be talking about this new GT key action below, but that’s what the “GT” part of the model number is all about.
It’s to let you know the GT (TP/400 Wood) is their premium key action for those people who care about getting the best piano playing experience they can get in a portable Studiologic stage digital piano. Nevertheless, Studiologic could have just made it easier and called it called Numa XGT. So I just call it XGT for my own reference and that’s the way I will refer to it here. ?


Piano Key actionSince key action is the most important component in any digital piano, I  am spending a good amount of time talking about this subject here. When it comes to key actions in stage digital pianos, they can vary quite a bit. It just depends on the brand and model of that piano. I have played many stage pianos that have springy key actions which feel more like keyboard key actions than piano. Other key actions I have played can feel very stiff or sluggish.  Other than Fatar/Studiologic, the primary brands who make stage digital pianos include Kawai, Yamaha, Roland, Casio, Korg, Kurzweil, and Nord,
Roland, Kawai, Yamaha, Casio, and Korg have their own proprietary key actions, and in this XGT model, since the Studiologic brand belongs to the Fatar company, this GrandTouch (GT) key action is proprietary in the XGT model. The key action has a specific model name called TP/400 wood. This new key action definitely has a few things going for it.
First of all, as far as the key movement goes, it actually feels good and is, overall, fairly comfortable to play. I have played on it for many hours over many days and the more I played it the more I liked it. There are definitely some upsides to this key action and also some downsides. Every digital piano key action has upsides & downsides, and some more than others.
Studiologic TP/400 Wood key actionStudiologic calls this key action its TP-400W “GrandTouch” as I previously mentioned. This description would give you the impression that it has the touch of an acoustic grand piano. In a way it does and in a couple of ways it definitely does not. Actual Grand piano keys are all 100% wood inside the key. The GT key-action has wooden sides on the white keys to give the white keys more strength and durability along with making the sides of those keys look more realistic. But they are not 100% wooden keys. The black keys of the GT key action are all plastic which is fine and I was expecting that.
Acoustic grand piano key actionActual acoustic grand piano keys are very long in length inside of  a grand piano. The white keys of a grand piano can be about 19″ long and they get much longer than that as the grand piano gets larger, such as concert grand pianos. The Studiologic GT actions have much shorter keys than real grand pianos (all normal digital pianos have shorter keys than grand pianos) and the keys are not 100% wood like acoustic pianos (as I just mentioned), so the balance and fulcrum points of those keys are not the same as grand pianos.
As an example, it takes noticeably more finger force to play towards the backs of the keys (flats & sharps) on the XGT as compared to the fronts of the keys. With a real grand piano it is virtually the same weight or finger force that it takes to play anywhere on the key because the key stick is so long and the balance and weighting is different.


Piano key action down-weightThe actual weight of the GT white keys going down and coming back up feels very good overall.  This is called static down-weight and upweight force as measured in grams. The white keys are especially impressive in their key weight and movement for a model in this price range. The amount of force it takes for your finger to press down the middle C key towards the front of the key, which is called static down-weight (aka: touch-weight), is about 57 to 60 grams of force. On a good grand piano it averages about 50 to 60 grams of finger force to play the middle C key, so the XGT key action is in a very good and comfortable range.
It is important to note that as you move your fingers further into the white keys towards the back, the down-weight force gets noticeably heavier which means the keys are firmer to press down. This situation is not necessarily unusual because it occurs on just about all digital pianos in this price range. Actual grand pianos or high-end digital pianos with longer key key actions would not have near as much disparity in this way, as I already mentioned. But it is worth noting.
Piano key action upweightThe return force of the keys when they return to its resting position after pressing them down is also important because those keys need to come back quickly and responsively without being too sluggish or coming back way to hard. This is called up-weight and the upweight on the XGT middle C key is about 30 grams based on my measurements.
This means that the key does not come back up too forcefully, which makes playing those keys more comfortable to play. However, some people might prefer a quicker key return upweight, especially if they are playing lots of musical trills. But a fast and harder up-weight does make the overall key movement noticeably firmer.  I do like the weight and key movement on the white keys, they are comfortable to play, and they do have  reasonably good acoustic piano feeling to them.
Heavier black keysAs for the black keys, they are heavier (firmer) than I would like to see. The middle C# key weight force measures are at about 77 grams of down-weight force and about 23 grams for the up-weight force of the middle C# key, based on my measurements. This would mean that it takes noticeably more force for the fingers to play on the black keys as opposed to the white keys. This is not necessarily unusual for some digital piano key actions and I have seen this before.
But it is noticeable that the black keys are firmer and heavier to push down as compared to the white keys and also as compared to regular acoustic grand pianos. The lower up-weight return force of the black keys is lower than normal and for some people it might be a bit too slow…or perhaps sluggish at times. But for me, the relative down-weight to up-weight force in the black keys is OK and I don’t find it to be an issue, at least for me. It’s just firmer/heavier to press down than I would otherwise like to see.
Piano key actionBut as far as perfection goes, the closer the white and black keys are to each other when it comes to key movement upweight and down-weight force, the better. Having the black keys be heavier than the white keys is not necessarily a bad thing and some people actually like it that way. It’s better than having the black keys be noticeably lighter in weight than the white keys. But I would have preferred if the black keys were less heavy and closer to the white keys for their weight and key movement. Nevertheless, this TP/400 wood key action is definitely playable and overall I do enjoy playing it
Another important feature of the key action is that it has “graded” weighted keys which means the keys get slightly lighter to the touch as you go up the keyboard (to the right) in the higher octaves and the keys get slightly heavier as you go down the keyboard to the lower octaves. This weight change is very incremental and subtle, but it does mimic what a real acoustic piano does in that way.


Key action escapementThe key action also has a feature built into it called “escapement” (aka: let-off). This is a function of acoustic grand pianos where there is a noticeable notch or hesitation of the keys as you press the keys about half-way down and play lightly and slowly on a grand piano. Some players like this feeling because it gives their fingers a  physical guide as to how fast (or slow) the keys are moving when you feel this “notch” feeling when playing the keys slowly and lightly.
Key action escapeHowever, you definitely don’t feel this slight hesitation (notch) in the movement of grand piano keys when you are playing at medium speed/key force or harder. It’s only felt when you play softly that you can feel it. This key action feature is nice to have, but in a stage digital piano it is not necessarily a deal-breaker in my opinion if it doesn’t have this feature. It won’t change the weight or overall movement of the keys. But for some people they may appreciate having it and will use it accordingly.


Ivory feel keysThe white keytops have a synthetic ivory material on them (ivory-feel) and it feels great. Not too textured and not too slippery…just right. It also makes the keys look a bit classier that way and better than just all-plastic keytops as some stage pianos have. The black keys have a smooth black matte finish on them which also feels nice and looks good too. So when it comes to a responsive dynamic key movement and overall comfort, Fatar/Studiologic did a good job with this new key action, especially in this lower price range.


Triple sensor - fast piano playingOne more thing. Digital piano key actions can have either 1, 2, or 3 electronic key sensors under each key. Sensors is what the keys need to activate the sound you hear. Having 3 high quality key sensors under each key is very important, especially for more advanced piano players. The additional key sensors for a triple sensor key action helps with having better note response when playing faster and with more repetition.
The XGT has a triple sensor key action with higher quality key sensors under the keys to give the player the sound response that will be needed when playing piano and other instruments where accuracy and speed is important. Other stage pianos in or around this price range sometimes only have 2 key sensors (or less) and those electronic sensors might also be poor quality which certainly does not help. So the key sensors in this XGT key action are good for what they let you do when playing your music, especially when you are at a more advanced playing skill level.


Noisy key actionHowever, there are a couple downsides with this TP/400 key action. These downsides (cons) will affect some people negatively and other people will not be bothered by these issues. It just depends on where you are playing this piano (home, studio, church, school, stage, etc) and your experience in playing other pianos.
The XGT key action is noisy. The downward key movement makes a noticeable thumping sound when the they hit bottom after you press down any key. If you press down the keys lightly then that thumping noise is not as loud and not bad, although you can clearly still hear it. But once you play a bit harder or more aggressively, then the thumping of the keys is very noticeable. It’s louder on the white keys than the black, but the black keys are still “thumpy.”
key action knocking noiseIt’s almost as if there is not enough padding under the keys to reduce that key thumping noise. This thumping/knocking noise is not quite as noticeable on the black keys when those keys hit bottom, but it’s definitely still there and you can hear it.
My guess is that Fatar/Studiologic certainly knows this noise exists but thinks their key action is so good that people will overlook that key action noise in favor of a good, responsive key action playing experience. However, if you want or need a “quiet” key action when the keys are moving then this one definitely won’t do that for you and I would suggest you don’t buy it.
Piano keys movingHowever, when the keys are coming back up to resting position on the XGT, then that part of the key movement is relatively quiet. There is still a small bit of key noise when the keys come back up, but it’s acceptable and normal and should not bother you at all. So that’s a good thing since some digital pianos have very noisy keys when the keys are coming back up.
Also, when the keys come back up there is minimal “bounce” to the keys. This is also a good thing because you don’t want keys wiggling or bouncing around when you let go of the keys and they come back up. So Studiologic did a very good job of making sure the keys are stable with minimal “bounce” on both white and black keys when they come back up after pressing them down.
But as far as the keys going downward and hitting the bottom of the keybed at normal speeds, you will clearly hear a thumping/knocking sound. If you are playing at higher velocities then people in that same room or a nearby room will also hear that noisy, thumping sound, especially if you are in a quieter environment.
Numa X Piano GTAlso, since there seems to be a lack of padding under the keys (it likely had to be designed that way), the keys hit harder when they go all the way down and you can physically feel that “hardness” in your fingers if you are more sensitive to that kind of thing. It can be a bit uncomfortable playing that way for some people and can be a bit fatiguing as well, depending on your fingers. But, if you are in a noisier area, playing on stage, in a noisier room or venue, and/or played piano before, then the “thumpy” key action noise and slightly “harder” key feel will likely not be an issue for you.
But…if you want or need a quiet and more comfortable key action playing experience, especially when playing the keys with a bit more force, then this TP/400 key action may not work for you. If you plug in headphones for private playing but there’s other people in the room, those people will most likely hear the thumping of those keys if that room is quieter, and they may be bothered by it. So just beware of that.


Numa X Piano GT Key ActionThis new key action moves very well, the keytops feel good, and the key movement is quite responsive, and I like it very much for those qualities. However, the thumping noise it makes can be disconcerting for certain people depending on your playing situation. Just so you know, you can always find “fault” with key actions for both acoustic & digital pianos because in most (but not all) cases there is no perfection. But it’s good to be aware of what’s going on, and so that’s why I try to give “full disclosure” to let you know the good & the bad. Putting aside the downsides of this key action, personally I really do like it and enjoy playing on it.


Grand pianoThe next most important thing to me when it comes to any piano is the realism of the piano sounds. Everyone wants their digital piano to have great piano sounds, but depending on what you get, those piano sounds may not be good. So you need to be careful of what model you purchase so you can be sure those piano sounds are as realistic as possible in your price range.
There are two kinds of piano sound technology these days which are sampling and physical modeling. Some digital piano companies use one or the other and a few digital piano companies use both technologies together. Using both piano sound technologies together is by far the best way to capture the acoustic piano experience in a digital piano. The better the technology in capturing those piano sounds, the more you will enjoy it and want to keep playing. It’s not just the technology itself, but it’s what the digital piano company does with all that technology to recreate those grand and upright piano playing experiences.
Musical color and expressionThe piano sound needs to be expressive, full of musical color, changing in tone and timber depending on how hard or soft you play the keys and/or how quick or slow you move the keys. Getting the subtle nuances you would get in a real grand piano such as the overtones, vibrations, acoustic noises, cabinet vibrations, string resonances, and all the other complex organic elements that happen when playing a top acoustic grand piano is what makes a digital piano either great, average, just OK, artificial and somewhat fake, or poor and sounding like a toy.
Also, good tonal and volume balance in those pianos sounds from one key to the next and from the bass octaves up to the treble octaves is very important. The volume of the piano sound in each key needs to be smooth and dynamic and the tonal elements need to come out naturally which is not easy to do in any digital piano. Real acoustic pianos are very complex instruments and many digital pianos, especially those under $2000, still sound somewhat electronic when it comes to their internal piano sounds.


Grand piano stringsDid you know that real acoustic grand pianos have about 230 strings in them with some are combined together (2 or 3 strings) to make one note? They also have approx 70 dampers that will stop those strings (with dampers) from ringing and sustaining when the when you want that to happen? The strings are installed in specific groups with certain materials and densities for those strings. The dampers are also different in size from each other depending on the strings they cover. In other words, the piano sound in a real acoustic grand piano is very complex especially in the top name brands, both mathematically and audibly. Then of course there are 88 hammers striking those strings and those hammers need to sound percussive in nature.
With all that in mind, and after playing the various piano sounds in the XGT piano library of internal pianos, my initial reaction to the realism of these different piano reproductions was most of the acoustic grand piano sounds in the XGT piano sound library are very impressive. They are not perfect (what digital piano under $2000 is?). However, I must say that in fact they are at least as good if not better than any digital piano I have played under $2000 for sure, and even under $3000…and that’s really saying something.


Yamaha grand pianoThere are 4 main stereo grand piano sounds recreated from a German Steinway grand, American Steinway grand, Japanese Yamaha grand, and Italian Fazioli grand. These piano sounds are specifically referred to in the XGT as “German, Japanese, American, and Italian.” They don’t use the brand names because of copyright and brand ownership restrictions.
Then there are 4 more secondary stereo grand pianos which are called Vintage, Austrian, Blu, and Pop. The 4 main grand piano sounds can be big, bold, and powerful with huge bass string dynamics and they can also be more subtle and delicate with smooth tonal and volume changes depending on the velocity of how you strike the keys.
The Steinways, Yamaha, and Fazioli, piano along with the Austrian Bosendorfer piano sounds are distinctly different from each other with their own individual tonal personality. It just depends on the type of music you’ll be playing as to which piano sound will fit your musical needs. But they are all very good and they allow for a big range of musical expression and dynamic tone quality.
Fazioli grand pianoThe only piano sound in that group that I thought needed some real “tweaking” was the Italian Fazioli concert grand. This is because it came out sounding much too bright and metallic, especially if you play with more finger force. But if you like a brighter and more metallic grand piano sound with a big bass sound at the same time in the lower octaves that can all really “cut through” and be heard above other players (if you are playing in a band or with other players), then the Fazioli grand sound will definitely do that for you and is impressive in that way.
However, a good solution to the brighter, more metallic Fazioli grand piano sound was for me to go into the EQ section for that grand piano sound and reduce the high frequency EQ setting which then took out much of that twangy sound, but not getting rid of it altogether. I still wanted some metallic character out of that sound so reducing it in the effects section did help, so then it was more usable.


Warm or bright piano soundsWhen it comes to grand piano sounds I have played just about all the great acoustic grand pianos out there for decades. I have played big Bosendorfer grands, Yamaha, Kawai, Steinway, Bechstein, Fazioli, Boston, Bluthner, and a bunch of others. So I know what they sound like and feel like to play. Different models within the same brand can play differently. So that means there is a lot of variety out there.
However there is generally 2 or 3 categories of grand piano sound which is called bright and very clear, warm and more mellow & resonant, and somewhere in-between. Some people prefer the piano sound one way and other people other ways, and this is because we all obviously have different ears and we hear things and react to them in different ways.
grand piano hammer striking stringsHowever, overall, I would consider the internal grand piano sounds in the XGT to a bit on the “bright” side and somewhat percussive. I happen to enjoy a piano sound like that so for me it’s a good thing. It’s especially true if the percussive attack part of the piano hammer sound (when the hammers strike the strings in a real piano) is realistic and organic in nature. Studiologic definitely got it right on the XGT for all 88 notes, which is not an easy thing to do.
However, depending on the music I am playing, I also like a more mellow/warmer tone or somewhere in-between. Fortunately with the XGT you can edit your piano sounds in a number of ways so that you can get your own customized piano sound to be brighter and more percussive or to be “warmer” and more mellow, but still with good dynamic tonal range.
grand piano voicingIn the world of acoustic pianos, changing the piano tone can also be done and it is called “voicing the hammers.” A skilled piano technician can actually modify the hardness and or softness of each felt hammer so that when those hammers hit the strings as the piano is being played, then the piano sound will be softer/warmer or harder and brighter depending on what that technician did to those 88 felt hammers.
It’s a long and drawn out process to do that on an acoustic piano and it is fairly expensive to have done. The technician needs to use special tools on the hammers and if that technician is not good at doing that job then they can really mess up the hammers bad. But…it can make a huge difference in the overall piano tone in an acoustic piano if that technician knows what they are doing.
Grand piano voicingI have personally seen this process done on Steinway, Yamaha, Baldwin, Kawai, and other grand pianos, and if the technician knows what they are doing then the outcome can be pretty amazing!
This “voicing” of the piano hammers in an acoustic piano is essentially what you get out of the XGT piano sound when you edit specific digital features and functions for each grand piano sound. You are really just “voicing” the “digital hammers” but you have to “tweak” certain parameters to make the changes in the piano sounds.
Editing controlsYou can set up and edit different parameters in different sections of the XGT using the color display screen to see what you are doing. This custom editing will directly affect those internal grand piano sounds and make them more mellow, more resonant, in-between, and even brighter if you prefer them that way. You just need to know how to do that on the XGT and also which controls and features you need to use to make those adjustments. In other words the preset internal grand piano sounds are not set in stone.
Favorites menu fo saving favorite programsI personally made some different adjustments with the editing controls and doing that had a big effect on the outcome of the piano sounds. You may already love the piano sounds that are in the XGT. But if you want to adjust them then you can and it’s not difficult to do. You can also save your custom piano sounds to a “favorites” menu and name that menu (such as “warm pianos”) so you know what’s in there. I made changes to different piano sounds including the German and Japanese grand piano sound and it did make a big difference.
Finally, the type of speakers and/or stereo headphones you use when playing the XGT (or any digital piano or keyboard) has a profound effect on the piano sound that you are hearing. So just switching speakers and/or headphones may be all you need to do if you want a slightly different sound quality. So just keep that in mind.


Piano bass stringsAs far as bass strings go in a grand acoustic piano, the bass strings are the thickest of all the strings and they are there to give you a big, bassy sound. Did you know the dampers that are on the piano strings (for nearly all strings) are there to stop the piano sound from sustaining when you play those notes and then let go of the key? In a real grand piano, when you play the notes where the strings have dampers on them and you let go of the key right away (staccato playing), the piano sound will immediately stop on nearly all the strings, with one exception being the bass notes.
The strings in the bass octave section are so long and so thick in a large grand piano that when the damper goes back down on any of those lowest strings after playing those notes quickly and letting go, it then takes a couple seconds for that string to stop resonating. That’s part of the overall natural physics and piano sound you get when playing a big grand piano, and it’s a good thing.
Grand piano stringsHowever, on almost all digital pianos, the lower bass notes immediately stop resonating and sustaining as soon as you release the key, which is how the other keys in the main octaves behave. In other words those bass notes don’t behave like they do in a real grand piano. The middle octaves and nearly all the other keys are supposed to stop making sound as soon as you let go of the keys, and that would be normal in acoustic & digital pianos. The very highest octaves in acoustic pianos don’t have dampers but the rest of the notes do have dampers. Dampers are very important or a piano could not play correctly.
grand piano bass dampersBut in a real acoustic grand piano, there are physics involved and the lowest octave strings don’t stop sustaining immediately when the dampers go back down on those notes. It takes a couple seconds for them to quiet down and that’s because those strings are physically so large, especially as compared to the rest of the strings in a grand piano.
With all this in mind, these XGT acoustic grand piano sounds have the bass strings with that slightly delayed cutoff when playing quick, notes without using a sustain pedal. You hear the bass strings act like they do in real grand pianos with a slight sustain when playing those low notes quickly, and that’s the way it should be.
If you have played real grand pianos before then you may know what I am talking about. I play big grand pianos and this bass note feature of a grand piano is one of the things that makes it sound so “grand.” Studiologic has recreated this low octave bass string experience, and when I heard it I was very pleased to see that Fatar/Studiologic thought of these relatively small but very important details when it comes to reproducing a more authentic grand piano playing experience.


Piano samplingWith regard to the overall piano sound in digital pianos, one of the downsides in using only “sampling” to record and produce the piano sound is the fact that the piano sound your hearing is a “sample.” This piano sample is a very short recording of the piano sound (about 2 to 3 seconds in many cases) and that sample is then electronically fastened together end-to-end and is “looped” so that it plays over and over. If the sampling process is done correctly then that piano sound can come out more normally.

Piano sample loop pointsBut the negative aspect of sampling is that typically you will hear the “loop point” which is the place where the sample starts and stops and then repeats itself over and over…like a hula-hoop going round and round. When you sustain that sampled piano sound then you can (in many cases depending on brand and model) hear that looping piano sound start and stop, like something is wrong with the sound.
Some of the cheaper off-brand digital pianos have a very poor piano sounds and the loops are so obvious you would thing something is wrong with the piano…but it’s just bad technology and a bad sampling process. Some of the better brands have a much better sampling process but those piano sounds still have audible loops.
piano sampling processWith the Studiologic XGT, they use a high end sampling process with special microphones set up in specific ways at a grand piano in a pro recording piano studio. Then they couple that recorded sound with their own proprietary physical modeling technology. Their main piano sounds do not have the obvious “sound looping” you would normally hear using just sampling technology alone. I did not hear noticeable electronic looping with their acoustic piano sounds except for one of the sounds here and there, and only while sustaining those notes for a period of time. It’s there, but you may not hear it.  I talk more about sample looping for the non-piano instrument sounds further down in this review.
Physical modeling piano soundsI did hear some definite string modulation and movement when sustaining those piano tones which is normal and good. However, from time to time, depending on which piano sound I was playing, I also heard a few anomalies in the piano sound, especially on the downward side of the piano decay time. These “artifacts” can and do occur on many digital pianos because they are electronic instruments after all. It’s relatively minor issue but it can show up if you play with longer sustain times.


Pedal decay time signAs far as the piano sound goes with regard to sustain decay time, this model is very good, but not perfect. Piano decay means how long it takes for the piano sound to fade out when holding down the sustain/damper pedal. The XGT has a reasonable amount of piano decay/sustain time and it really does sound fairly natural. Not only the decay time is good but also a natural volume during that decay time is fairly steady.
Sometimes, especially on cheaper technology digital pianos, the decay time may be OK, but the volume of that piano sound can fade out right away leaving you with no sustained piano sound, even though the decay is still going.
Sustain-decayBasically, there is a lot going on sonically when it comes to a real grand piano sound sustaining/decaying over time when holding down the damper pedal. There’s all kinds of overtones and sympathetic vibrations along with organic tonal elements due to the physical nature of a wooden acoustic grand piano. With all of this to consider, I give the XGT a definite passing grade for its ability to recreate convincing acoustic grand piano sounds and piano sustain, given the fact that it is an electronic instrument and not acoustic.
Sustain decay timeBut…real acoustic grand pianos have much longer and much bigger piano sustain and piano sustain/decay times and the XGT doesn’t come close to that. So if you are wanting to get this model to mainly play big classical piano music on it and are expecting musical perfection when it comes to the acoustic piano sounds, then you could be disappointed. But it is only $1999 after-all and perfection should not be expected in this price range. Nevertheless, as far as I am concerned the grand piano sounds are very impressive.


German Grand PianoWhether you are playing the acoustic piano sounds softly, quickly, hard and aggressively with different note velocities, with fast repetition, delicately, using the damper pedal, playing multiple notes and chords and having the notes mix altogether, in my opinion the XGT is a winner despite a few of its shortcomings. 
When it comes to expressive and realistic piano sounds, as long as you are not too demanding and not focusing just on complex classical music, this model offers lots of “musical color and expression” in surprising ways that you might not expect in this price range. 
Is it perfect in reproducing a top name acoustic grand piano like a Steinway or Yamaha?…no it is not. The piano sounds are obviously electronic with the sound coming from digital sampling & physical modeling, and after all, the sound has to go through speakers or headphones. But apart from that, it sounds great, especially if you do a little editing and “voicing” on the piano sounds if you feel it’s necessary.
headphonesSpeaking of headphones, the grand piano sounds (as well as the instrumental sounds) really sounded great through my stereo studio headphones. Sometimes the sound from a few of these digital pianos through headphones is just mediocre at best. But in this model the sound through a good pair of headphones was very “alive” and well balanced from the bass octaves through treble octaves, so I was impressed with that especially since I do use headphones quite a bit.
When it comes to piano playing on a digital piano in this under $2000 price range, the XGT comes close enough to making you feel that you might be playing the “real thing.” In my opinion, for most people who appreciate the XGT for what it is, the acoustic stereo piano sound technology the XGT generates (assuming you are connected to some quality monitors or headphones) is very satisfying to listen to and play, it feels and sounds “alive,” and it will draw you back to wanting to play it often….and that’s a very good thing.


PolyphonyThe word “polyphony” means how how many notes can be played on the keyboard without dropping out. Polyphony is the piano and instrument processing power, and depending on how much total polyphony a particular model has, the end result is that your music might be affected if the instrument does not have enough polyphony for your needs.
Polyphony is generally rated in mono. So when a specification says 256-note polyphony then it means that number is the maximum notes that can be played if the sound is in mono. If the specific sound that you are using is in stereo as is the case with most sampled acoustic piano sounds, then stereo would be half as much as mono.
300 note polyphonyThe XGT is 300 note polyphony (maximum) which sounds like a lot, and it is. So that’s a good thing. The word “maximum” means the total amount of polyphony at any one time in mono. With the XGT having many stereo piano and instrumental sounds, 300 divided by 2 is 150. So there would be 150 notes of polyphony if you are playing a stereo grand piano sound.
Since there is only 88 keys on a piano and you won’t be playing all 88 keys at one time then 150 notes of piano polyphony is more than enough. However, if you set up a “program” with 4 separate piano and instrument sounds layered together and you play all 4 at one time, then that where polyphony really becomes important because each instrument is taking up and using it’s own amount of needed polyphony.
4 instrument sounds layered together on XGTIn other words, when you play 4 sounds together like you can on the XGT, and some or all of them are in stereo, the nearly all of the polyphony might be used up especially if you are playing a lot of notes at the same time and also using your sustain pedal. So on the XGT, being a stage piano that can have a lot of sounds and effects all going at the same time, you need to have a lot of polyphony processing power so that you do not have noticeable “note drop-out.”
My playing experience on the XGT was such that I did not notice much note drop-out at all. It did happen occasionally when I mixed all stereo instruments and played a huge amount of notes with lots of sustain time. But few people will likely play music like that because I tend to “over-drive” and test things out to its “max.” But even when I put 4 stereo acoustic piano sounds together at one time, I did not get any note drop out.
check markWhen it comes to the polyphony specification, 300 notes of maximum polyphony is more than the majority of what digital pianos have these days. The higher quality of the internal instrument sounds in the XGT are overall able to handle the 300 note maximum polyphony in a good way without issues. Having enough polyphony in a digital piano is very important to me because I tend to “max out” the piano with mixing as many stereo instrument sounds as possible along with using a good amount of sustain with my sustain pedals. I don’t want “note drop-out” if I can avoid it and I would definitely give this model a passing grade when it comes to its polyphony technology and ability to cover up to 4 instrument sounds at one time.


piano pedalsMost people who play piano know how important the pedals are in helping to produce realistic piano sound. If the pedals are not working correctly and doing what pedals are supposed to do, and the piano sound is not reacting naturally when using those pedals, then that’s a big problem for me. This is especially true of the damper/sustain pedal.


Numa X GT triple pedal unitThe XGT comes with a triple pedal unit. Many stage pianos only come with a single pedal and sometimes that pedal does not have half-damper ability. Some stage piano companies don’t have an option for a triple pedal unit or don’t come with a triple pedal. So to get a triple pedal unit with this piano that can be programmed and have lots of good control over the instrument sounds is is very good to have. The half-damper sustain pedal control gives you a variable amount of sustain instead of just off & on sustain. If you are a piano player then you will appreciate this feature with the sustain pedal
The Studiologic triple pedal is portable and just lays on the ground and does have a bit of weight to that unit. The pedals are easy to push down (actually a bit too easy), they are fairly quiet when they go up & down, and they control the normal aspects of piano pedals. The pedals include the sustain/damper effect, the sostenuto function, and the soft pedal function. So the pedals should be able to perform properly with your piano playing and keep up with your music.
triple pedal functionsAlso, the triple pedal unit can be programmed to do other functions. This would include selecting pre-saved instrument registrations/programs and move them up or down in a particular order while you are playing so that you can remotely select new sound setups for the keyboard with your foot without taking your fingers off the keys to do that. You can also plug in two separate single pedals and program those pedals to activate pedal functions in the piano such as expression pedal, separate continuous controllers, and so on.
So when it comes to pedal functions along with the included triple pedal unit, there are more than enough things you can do with the pedals to control the XGT and have a better piano and keyboard playing experience. After all, this XGT model is a “controller keyboard” and the goal of Studiologic is to give you control over the sounds you are hearing so that you can interact with those sounds in some very helpful ways by using the pedals. The measurements of the triple pedal unit is 10.5″ wide x 8.5″ deep. The length of each pedal is 3.5″.


vintage electric piano soundsWhen it comes to the vintage electric piano sounds in this model, there are a lot of them and they are very good. The sustain time and sustain quality when using the sustain pedal is equally important for the electric piano sounds. I found the quality and length of sustain time for those vintage electric piano sounds to be quite impressive . This helped to recreate the older vintage piano sounds (along with Studiologic DSP effects) that people like and can be very enjoyable to play depending on where you are playing and the type of music you want to do.
I personally love playing those vintage electric piano sounds, especially when their sustained tones can be reproduced in an a more authentic way, and the XGT does that really well in my opinion. The non-piano instruments also work well when controlling their sustain time from the triple pedal unit or an optional single pedal that you can get for the XGT.


Sustain pedalWhat I mean by “continuous pedal sustain” (aka: pedal hold) is that it allows the non-piano instrument sounds like strings, horns, synths, organs, etc, to have continuous sustain without any decay as long as you hold down the sustain pedal. In other words, instead of that sound being percussive (staccato) and immediately stopping when you release a key after pressing it down, these various instrument sounds can continue to sustain and hold as long as you hold down the sustain pedal. It would be like a trumpet or violin to be heard continuously as long as you keep that sustain pedal down. This feature can add another dimension to your music and is very useful. Other brands such as Yamaha cannot do this.
Sustain pedal - global assignmentThose instrumental sounds can also be held and sustained just by holding down a key (which is good). But having the sustain pedal do it gives you pedal control over all sounds in the mix and each instrument sound can be adjusted to have the continuous sustain or not have it depending on what you need.
If for some reason you don’t want those non-piano instrument sounds (strings, horns, synths, organs, etc) to have continuous sustain when holding down the pedal, then you can shut off that feature in the pedal editing controls and then those instrument sounds will stop playing as soon as you let go of a key. It’s really up to you how you want that to work depending on the type of music you are playing and what you prefer.  The XGT is more flexible in that way as compared to some Yamaha digital pianos (as an example) since some of those models do not have continuous sustain capability for their instrument sounds


Piano sustain pedal giff

Another really cool aspect to using pedals on the XGT is the organic nature of the damper-sustain pedal. In a real acoustic grand piano when you press down the damper-sustain pedal, that pedal pushes the physical dampers off the strings of a real piano by lifting up the damper rail which takes the dampers off the strings so they can all sustain. When those dampers lift off the strings then you can hear an echo noise of all those strings starting to resonate. When the damper-sustain pedal is released then the damper rail with their felt dampers comes back down onto the strings to stop the strings from resonating in a real grand piano.

Damper pedal noise control featureWhen that damper rail comes back down it creates some “pedal noise” like a small little mechanical “clunk.” You can hear and feel this sensation in a real grand piano, and those people, like myself, who have played grand pianos for a while know what I am talking about. The XGT can recreate these resonations and damper rail noises perfectly when using the triple pedal sustain pedal. There is a digital feature called “pedal noise” which is programmed into the piano sustain control for the XGT.
You can control the amount/intensity of pedal “noises” that you get when you use the sustain pedal on the XGT and it absolutely sounds real. It definitely adds an organic feeling when using the pedals as you are playing piano on this instrument. A very cool feature (it really is) and not one that should be overlooked.
So when it comes to the included triple pedal unit, Studiologic hits a home run on what it can do, how it does it, and the easy programmability of the pedals from the user interface to do what you want them to do.


218 instrumental sounds in 8 sound groupsIn the XGT there are 218 individual instrument sounds divided up into 8 groups which include all of the piano sounds. There are also 2 different drum kits on board with many individual percussive sounds per kit. As with many digital pianos with instrument sounds, many are excellent, some very good, and a few are OK. There are pianos, electric pianos, strings, synths, orchestral, organs, brass, guitars, and just about anything else you could want.

Piano sound libraryIn my opinion and based on years of playing experience, it’s not how many sounds you have in your digital piano or keyboard that count, but it’s the realism and authenticity of those sounds that matter. I’d rather have a couple hundred awesome sounds then 1000 mediocre sounds when it comes to playing music.
The XGT internal sound library has noticeably more authentic stereo instrument sounds when playing them individually or layered/split than many other brands or models that I have played before, especially in this price range. The stereo sound field is also impressive with these sounds and it really adds to the overall authenticity and organic nature of what you hear.
Orchestral sound libraryNot only are many of the acoustic grand piano tones impressive as I previously mentioned, but many of of the strings, organs, and orchestral sounds are really outstanding. You can put together an entire concert of organs, orchestral sounds including various brass and woodwinds, mix them together (as I discuss below) and be able to create some very inspiring and realistic musical orchestral scores in real-time in ways that most other digital pianos cannot do. Definitely a more natural, organic musical experience with these instrumental sounds on the XGT.
XGT synth sound libraryOne of the other nice things about these instrument sounds is that you can use the special effects section of the XGT to enhance those instrument sounds and make them even more realistic. The special effects section is important to these sounds and they really can make a huge difference in the outcome in terms of realism and enjoyment. You can do many things which include adding an adjustable stereo spread to the sound, reverb variations, and a variety of other effects depending on what you need. It just depends on which instruments you are using from the sound library categories and the effects will enhance them. I will talk about the special effects section further down in this review.


sample loopingOne thing I did notice with a some of the instrument sounds in the XGT is many of the instrumental sounds had some noticeable “looping” going on when you sustained some of those instruments sounds such as brass, some orchestral, some guitars, some synths, etc. These sounds are “sampled” and one of the well known downsides to “sampling” is the fact that samples are actually just very short recordings of the actual instrument sounds with the recordings being a couple seconds long of so and then that short recording is tied or “looped” together to form a continuous sound.
Hula hoop movingIf you hold out that sampled sound on the XGT or almost any digital piano by pressing down a key and holding it, that’s when you can hear the loop beginning and end point, and that looping continues on until you let go of the key. This noticeable looping only really shows up when you hold out an instrument sound like trumpet, violin, etc for multiple seconds. If you let go of that sound somewhat quickly with your finger or your sustain pedal, then you don’t hear the “looped” portion of the sound.
But if you sustain that sound for a few seconds or more then that’s when you hear it. For most people this issue won’t be a problem although it’s typical on most digital pianos out there with high quality samples such as what the XGT has. It is just a by-product of the process for these types of no-piano instrument sounds. It’s a bit like a hula hoop that starts and keeps revolving until you stop it. That hula hoop as a beginning and end point and keeps looping.
Vocalpad soundOne of the instrumental tones where I really noticed it is called VocalPad. It’s a full sounding mellow pad tone combined with a synth-choir sound, and that combination sound is very nice and usable for a variety of music.
However, the VocalPad tone had noticeable short repeating loops about every second to 1-2 seconds when holding down a note(s) or using the sustain pedal. and as loops do, they modulate the volume of that sound up & down fairly quick. Again, this is a common occurance in many digital pianos these days and I also noticed the same issues with some string sounds, horns, etc.
sample loopingBut…in most cases you would not necessarily be sustaining those sounds long enough to hear the looping or you might have that sound combined in a layer with other sounds and most people would likely not notice it that way. But if you do sustain that sampled instrument tone and you are listening to it and sustaining it by itself and not layered with other tones, then you will notice it if you listen for it.
When I test out digital pianos with additional sounds I usually try to play those sounds in almost every way possible. I do this so that I can hear any anomalies if they are there. In the “real world” of playing music, most people may not be using and playing these instrument sounds in the way that I do, so they might not hear any of the issues I am talking about. Nevertheless, there are some instruments in the XGT such as strings, pads, organs, and vintage electric pianos that are outstanding in authenticity. They are really enjoyable to play and add quite a bit of realism to the overall playing experience.


Program select menuThe XGT has a feature called “Programs.” You can insert and save up to 4 instruments of your choice in a “program” out of the 218 internal instruments. You can put them in any order and in any configuration in any of the 250 program spaces available in the XGT. You can quickly access any of the 250 programs by a single knob and once you locate the program you want then you can simply play and get the sound setup in that program. You can play the various instrument sounds in each program by themselves or in combination with each other or split them up among themselves, or a mix of that.

Program sound splitsThe XGT is capable of mixing/layering up to 4 separate instrument sounds together or assigning up to 4 instrument sounds to be split into different “zones” on the keyboard. You can have each sound on different sections of the keyboard as well as mix them together and put each sound in those sections in any octave that you need. So the XGT is very versatile in that way.
 Also, controlling other aspects of those instrument sounds is fairly easy and intuitive with those immediate analog control knobs and buttons and really makes your music sound great because you can adjust things quickly for each sound. I will talk about the user controls for the instrumental sounds including layers and & splits further down in this review.
4-part orchestral layerThe XGT really “shines” when you do a 4 layer mix or splitting of different sounds. It’s one thing for a digital piano to be able to mix/layer together 4 sounds. But it’s another thing for those sounds to be mixed so their touch velocities compliment each other, their instrumental volumes and voicing “cut through” the mix so that you can clearly hear each one up and down the keyboard, and so that they just sound good together. That kind of thing is no easy task.
Being able to layer or split multiple sounds can be very musical inspiring and allows you to do musical things that you may not otherwise be able to do. It’s really helpful to be able to mix together up to 4 acoustic piano sounds, or up to 4 vintage electric piano sounds at one time, or have an acoustic and electric piano along with a pad and strings. Or maybe a stereo synth, percussive marimba, Japanese Yamaha grand piano, and Hammond drawbar B3 sound all together.
XGT acoustic guitar set - layersThe acoustic 6-string steel string guitar is surprisingly good and even better when you use the effects section to add to the realism of that guitar through EQ, chorus, reverb, a bit of delay, etc. Then you can take that acoustic steel string and mix it with the Italian Fazioli grand piano and a touch of stereo pad along with a very nice 12-string guitar and add a stereo phaser 100 to that 12-string and you get a “mind blowing” acoustic set that is beautiful and least I thought is was.

3-layer sound with classical guitarI like to do different musical things on a digital piano, particularly if it has that capability. I like to “experiment” and come up with different mixes that you may not typically hear on a digital piano but yet are things that are enjoyable to hear and can inspire you to play. Since I play guitar and have for many years along with owning some good ones, I know what guitars are supposed to sound like and I definitely am a guitar guy. But I’m also a piano guy (and organ) too since I play them professionally, and I love to play big, beautiful grand pianos.
So when I can combine my love for piano with my love for guitar and then blend them together and put a good pad in the background to fill everything in, then for me that’s something which I love to do and the XGT lets me do it well. Plus, it’s intuitive and quick to do that kind of a mix on this instrument which is important. What’s the point of having hundreds of things that you can do on a digital piano but get lost in a sea of incoherent menus or that just take to much time to navigate or make quick changes.
organs, piano, bass - layer & split

But based on my extensive playing time with these various instrument sounds on the XGT including time playing and listening to the reproductions of Hammond B3 sounds, vintage organ sounds, pipe organs, acoustic & electric guitars, acoustic pianos, vintage electric pianos such as a variety Wurlitzer’s, Rhodes, Yamaha DX7’s, and others, I must admit they are impressive and very musical. Along with horns, a variety of strings including orchestral, chamber strings, and a variety of solo strings and all of the other instruments, I can safely say that you will be very happy with the way they sound.


acoustic upright bass bandEven the upright bass sounds such as acoustic upright bass 1 is clearly more realistic than many others I have played in other brands and models of portable digital pianos. When you play a note and move down from middle C all the way into the lowest octave, you hear natural sounding organic changes in the tone of those acoustic bass sounds as you play the keys with more or less force.
upright bass playerYou hear such things such as the fingers slapping the bass strings when you press the keys harder, the strings resonating in different ways depending on the notes you are striking on the keys, organic wooden sounds that you might hear coming from a large wooden acoustic bass, and even the strings themselves shaking and making acoustic string buzzing and mechanical/acoustic noises like you would get on the actual instrument. 
There are also the squeaks and string bending that you would hear out of a good upright acoustic bass if a pro player was playing one. All of those additional organic sounds in the upright bass tone depends on how quickly and or forcefully you are playing the keys on the XGT. It sounds great, especially when playing some jazz and splitting the keyboard. It’s much more enjoyable to hear than on other brands and models under $2000, and this is the case for a number of the other bass and instrument sounds in the XGT sound library.
Jazz band layer & split

There is so much “expression” and musical color that can come out of these instrumental sounds depending in part on how soft or hard you play the keys and/or how you use your pedals. The realism of these various sounds is impressive, and when you combine them together in layers of up to 4 instruments, then your music will be even more exciting. It’s almost like you have a full orchestra or band at your fingertips and controlling each player while you play…it can sound that good. I was certainly impressed.


Numa XGT smooth sound transitionIn some cases with some brands and models of digital stage pianos, you don’t always get a realistic library of non-piano instrument sounds, especially in this price range under $2000. Plus you don’t necessarily get good special effects technology & control to add to the sound realism. Plus, in this model, the XGT has what’s known as “smooth sound transition.” Some digital pianos have this feature and some don’t.
Smooth sound transition means that when you switch from one sound to the next sound while you are playing, the previous sound just doesn’t cut off and stop when you switch to the next sound as you are playing. On some digital pianos like many of the Roland models, when you change from one main piano sound to the next piano sound or you change from a main piano sound to an instrument sound then the 1st sound (the main piano) immediately cuts out and there is a break or interruption going to the next sound you have chosen.
Sound layer screenAlso, when you switch from one of the sounds in a 4-layer program you have set up on the XGT and you mute any one or more the those sounds in the 4-part layer, then when you unmute those sounds or mute them, they don’t just cut off immediately. Instead of cutting off you have a smooth sound transition from one sound to the next so that there are no abnormal breaks between sounds when you are playing. It’s like one sound is fading out naturally when you move from it to another sound rather than it just immediately stop.
When you are playing music, especially when playing live on stage, regardless of the venue, or in a recording studio, you want to be sure the digital piano you are playing doesn’t have any breaks in-between sounds while you are transitioning to another sound. You want it to be smooth and seamless and the XGT does that very well. 
It is important to note that you will have some “breaks” when you switch from one “program” to the next because of the entire program changing along with all of it’s individual effects. But those are not the individual sounds within a program or within the sound library. Those are up to 4-part sound programs with effects in them so switching among the many programs will not have smooth transitions, but that is completely expected and not an issue.


XGT 218 instrument soundsSo given that Studiologic has really gone beyond the norm in creating their 218 “essential” stage piano sounds, recording studio sounds, and general instrumental sounds for the XGT that most people want and that sound really good, you should be able to find the sounds that make your music “come alive.” There are always a few sounds that any digital piano may not have such as monophonic synth (moog, etc) sounds the XGT does not have. But there are other ways the XGT can help you get those “additional sounds” which I talk about next.
But for now those XGT internal sounds such as vintage organ sounds (really impressive with Leslie effects, etc), vintage electric pianos (equally impressive), pads, strings, brass, orchestral, and acoustic pianos that are there may cause you to have a difficult time turning off this instrument and walking away from it. At least that’s the way it was for me.


More sounds!Assuming you wanted or needed more instrument and piano sounds for the XGT than what is already in it from the factory, there are 2 additional ways to do that. The reason you may want more or different sounds depends on the style of music you’ll be playing and the actual instrument sounds that would work the best for you.
Personally I think the XGT has plenty of great internal sounds in it and normally you may not need anything in addition to those sounds. The XGT has all of the main sounds groups plus it has some special effects, percussion with individual percussive drum sounds assigned to each key, and all of the programs that you can customize for layers & splits.


Numa Manager appBut let’s just say you needed more or different sounds because you need something specific the XGT internal sound library doesn’t have. Well, you can easily do that and one of the ways is through the Studiologic Numa external factory sound library. You can download more instruments from the Studiologic web site with an app called Numa Manager by using a mac or windows computer. So beyond the 218 internal instrument sounds in the XGT you also have the ability to get more sounds from the XGT external sound library that you can download to from computer..
You can also manage those sounds along with your internal programs from the Numa Manager app for your computer so that you can arrange and control those sounds in an intuitive way from your computer rather than just from the XGT itself.


USB audio interfaceBeyond the XGT external sound library, the XGT also has a USB audio streaming interface. For me this is a bit more practical and a much quicker method of getting more instrument sounds along with more effects, drum rhythm patterns, accompaniment style patterns for a one-man-band setup, and also piano educational software apps should you want to improve your playing skills or teach someone else to play piano and keyboard.
If you are not familiar with USB audio streaming, this is the latest technology to connect with an external device like an iPad and stream audio from the iPad into the XGT. You can then use iPad music content apps to add to your playing enjoyment and hear the sounds from the XGT come through your speakers or headphones plugged into the XGT.
I use this method occasionally and it’s practical, fun, works well, and is easy to set up. It gives you even more flexibility with adding more more options to your music. You can still use the internal & external Studiologic sound library as well. But this is an additional method of getting “more.”
USB cableSome good examples of using USB audio streaming on the XGT is to first connect an external device like an iPad to the XGT. You would do this by getting the correct USB cable along with the iPad camera connector (a special cable attachment) and then plug in that cable to the XGT going out to the iPad. Once you are done with that then you are officially connected.
assignable usb knobFrom there you have a special control knob called “assignable set” located under the master volume control and that knob can be assigned to USB audio or general audio input volume for any device that you’ve connected coming into the XGT. In this case you would assign that controller knob to USB audio. Once you do that then you press down on that knob and you can turn the USB audio streaming on or off whenever you want and also quickly control the volume of your USB device with that same knob.
USB audio onThe idea of USB audio is that when you connect to an external device like an iPad for your MIDI connection, not only are you connecting through USB MIDI going out of the XGT, but you are simultaneously getting audio from the iPad coming into the XGT. This means that whatever audio sound you are hearing in the iPad (external device), it will simultaneously come into the XGT and mix with any internal instrument sounds in the XGT or be heard independently from those sounds.
iPad with XGT audio interfaceAs an example, the XGT does not have any drum tracks and I like to play along with drum tracks (patterns) if I am playing music in my studio, on a solo gig, or just at home in a recreational way. So I can get  a drum pattern app from the app store (there are different drum track apps) and then I can select a drum style and tempo, and that drummer is heard through the XGT speakers or through headphones via USB audio streaming and I can play along. I can independently control that external drum volume by the USB volume knob on the XGT.
Audio interface with Garage bandAnother practical way of using USB audio is by getting instrument sounds from apps on an iPad, computer, (or iPhone) to control from the XGT such as cool synth and/or special effect sounds, more organs, electric pianos, strings, etc. A couple of examples of those kinds of apps might be Garage Band and/or Sample Tank, just to name a couple. There are many more apps (some have a cost, but they are reasonable) including acoustic piano apps such as Ravenscroft grand pianos, ivory, etc.
MIDI USBSo you select the program or app you want on your computer, iPad, or iPhone as an example, and then select the USB audio from the XGT and the adjust the volume you want to have from the XGT USB volume knob, which is super convenient and practical, and then you are ready. But first you must assign the iPad to at least one quadrant of the XGT user interface screen that would say MIDI USB. That’s easy to do and once it is done then you can also use all the XGT special effects and editing features on the USB sounds as well. So there is a lot of flexibility with this feature and it works well.
USB audio sound from external device mixYou can mix and layer the incoming USB instrument sounds from your external device (iPad, etc) with the internal sounds of the XGT in any configuration or split up to 4 sounds including the external sound into 4 keyboard zones for a split configuration. The possibilities are really endless and then you have the best of both worlds…internal and external sounds and it’s very easy to use them which is the key to success when wanting to use and change sounds quickly while you are playing, or just setting them up correctly.
So if and when you want to go beyond the internal instrument sounds in the XGT, then you have those two additional ways to do it. You can get more “free” sounds from Studiologic using a computer and/or also expand what you do musically by using the USB audio streaming feature. Also, with USB audio there is no latency because it’s not wireless…it’s using a USB connection which is instant sound as soon as you play a key, and that’s what’s you want. Bluetooth audio (which the XGT does not have) would not work well for audio streaming when playing live on the keys because it does have latency.


user interface
With all these piano and instrumental sounds in the XGT, and all that those many sounds can do along with the special effects section which can enhance those sounds in a number of ways, in my opinion it doesn’t matter how much a stage digital piano has in it if you cannot easily and intuitively access and control those sounds and effects. That’s where many of these digital stage pianos and keyboards run into problems and fall short…they are simply not easy enough to use, especially in real time when you need to make quick and effective changes to your settings.
Therefore a good user interface control panel is vitally important to your overall playing enjoyment. The Studiologic Numa XGT was built to not only have great sounds in it, but also to be a professional keyboard controller (for the pro musicians out there) giving you detailed user control over the various functions and features of this piano.

There are many ways to design and build a digital stage piano controller and there some popular models out there from the top digital piano brands such as Korg, Kawai, Roland, Casio, and Yamaha. So to compete against those recognized brands is not easy, especially if your product is more of a “niche” product. The Fatar/Studiologic names are not “mainstream brands like the other ones are. Professional players know those names but the more mainstream digital piano shopper may not have heard of them before.
Therefore, when a smaller brand with less name recognition competes against the “big guys,” that brand really needs to be innovative and produce a great product at a lower price than the other brands. That’s just how it needs to work. So when Studiologic came out with the Numa XGT and it started gaining a “following,” I just had to see what all the commotion was about.


user interface
Controlling all these very impressive piano & instrument sounds along with the special effects in an effective way is what it’s really all about….control. So when I saw and used this XGT user interface control panel for the first time I was really impressed and amazed that I had not seen something like this before and how good it is.
I make it a habit of trying to use a new user interface without reading the owners manual. I figure if I can use the features and functions of this model through its user interface and not get bogged down or confused by its operation and not forced to read the owners manual all the time to see how things work, then I am more willing to go through all the features and functions to explore them.
user interface controlsWith all that in mind I give this XGT user interface a grade of an A for its ease of use both during the day and at night when it is dark. I rarely give that high of a grade to a digital piano company concerning their user interface control panel. On most top brands their control panels have some good things that make using them easy and effective.
 But then they can also have some really frustrating things like deep and/or confusing menus that you have to go through to find the things you want and then figure out how to use them. In other words, menus and controls that are not intuitive  
user interface control panelIn my opinion this is not the case with the XGT user interface. Its relatively easy to figure out and even a child could probably use it effectively after playing around with it. The XGT user controls are not “childish,” but they are so easy to use (as compared to many of the other models out there) that someone young with little or no experience on this model could access and use the many functions very quickly with little effort. This is what you want out of a pro or home studio digital piano controller…quick and effective access to the sounds, effects and editing functions that are important to you.


4 color coded encoder knobsThe way the user interface works is there is a 2.8″ color display screen in the center of the control panel that is divided into 4 virtual rectangular quadrants. Each quadrant is color coded with a different lighted screen color. Each quadrant in the screen is assigned a number, 1-4..There are 4 sturdy controller (encoder) knobs just to the left of the color display screen and those knobs are all in a horizontal row. Each knob is assigned to an individual quadrant, and believe it or not, those knobs have light up color coded rings at the bottom of the knobs so that the knob colors correspond to the quadrant colors in the display screen.
Color coded controller knobs and display screenIn other words, everything is color coded so that you know which sounds you are controlling and you can make changes to your sound setups easily when you look at the corresponding colors on the knobs and in the display screen. As an example, you can assign up to 4 instrument sounds in the display screen at one time. Each quadrant (or zone) can have 1 instrument sound in it, although a few of the sounds have other instrument sounds joined to them in the one sound, You can use/play each sound individually or combine any two or three of them together in a layer, or you can use/play all 4 of those sounds at one time.
Sound editing and display screenWhen you assign up to 4 sounds in that mode, it is called a “program.” I mentioned the “program” feature earlier. You can save up to 4 sounds of your choice as a program and then use that program to play those sounds together or apart whenever you want to. Each one of those sounds in that program can be controlled and edited individually to change individual volumes along with a very big number of editable parameters for each of those 4 instrument sounds in that program.
4-layer custom programAs I mentioned earlier, there are up 250 user programs available in the XGT with the first 100 of them already programmed by Studiologic with sounds in each of them. You cam change the instruments and setups in those first 100 programs to your own custom settings if you wish. With 250 programs you have plenty of options for playing live, being in a recording studio, or at home for recreational playing. Having 250 programs is a lot and you’ll be able to make any type of sound setups you can think of.
Each program is like having up to 4 live instruments in a band or orchestra and each instrument within that program can adjust or turn its volume and functions on or off, set it’s octave that it plays in, its sustain, its reverb, chorus effect, stereo field, on so on. So you can customize each of those 4 sounds and then use those 4 color coded knobs to adjust the volume of each of those sounds in real-time.


Grand Piano layered programHere’s an example of a custom “user” sound setup that might be very useful to have in a program. I put 4 acoustic grand piano sounds together in one program, 1 in each section. This gives access to each piano sound so that you can quickly use them by themselves or in combination with each other as a 2, 3, or 4 piano layer. Yes, there would be some “phasing” going on when mixing 2 or more acoustic piano sounds together, that’s fairly common. But you can definitely minimize that phasing on the XGT when 2 or more similar sounds are playing at the same time, but it just depends on how you set them up as to how much phasing you might get.
Piano sound editing

Regardless, you can have any 4 acoustic piano sounds together out of the acoustic piano menu and save them in one program for quick and easy access when you want to use different piano sounds for different styles of music. You can also tweak each of those piano sounds individually, change volumes in real time, change octaves of any of them, apply effects from the DSP effects section and decide which pianos would have those effects, and set up each piano in exactly the way you want.

piano sound editingI did this with 4 acoustic grand pianos and played them 2 at a time, 3 at a time, and all 4 at one time. The combination sound of having, as an example, a Japanese Yamaha grand with a German Steinway grand piano was really cool and created a grand piano sound you cannot get by using those individual grand piano sounds by themselves. You can also alter the octave of each grand piano sound or split them into zones across the keyboard.
This type of program is easy to setup and save and you can do the same for any of the 218 instruments on the XGT. You can also set up a program to have 2 acoustic pianos in it along with 1 vintage electric piano and one stereo pad sound, or switch that up by changing pad to strings and vintage electric piano to acoustic guitar, and then mix all of that together as one complete layered (or split) sound program.   
3 grand pianos & one vintage electric - layerAn example of a cool program that is not about acoustic pianos is you can setup and save up 4 different vintage electric piano sounds in one program which sounds very impressive when you do that. You could also combine 1, 2, or 3 vintage electric piano sounds together with grand pianos to enhance the piano sound mix. This works very well and can give you hundreds of piano layer possibilities.
Also, when you pressed harder and/or faster on the keys, you got all those natural organic elements those vintage pianos would normally put out such as “dirty, gritty, or more percussive electric sounds. If you play those vintage instruments lightly on the keys then you get softer, more bell-like tones. So there is a huge range of expression for those vintage electric pianos along with a more ethereal, sustained pad tone going in the background depending on how I was playing.


muting layered partsAnother very interesting and useful feature of this 4 instrument mode is that when you have 2,3, or 4 instrument sounds layered together, if you want to mute one of those sounds all you have to do is just quickly push on the top of the volume (encoder) knob that corresponds with that sound and then that sound is muted. The color display quadrant of that sound turns to a dark gray color so you know it’s muted. If you want that sound to come on again you just push the top of that specific volume knob and then the muted sound light ups again in the appropriate color and it’s part of the mix again.
4 part layer - onBeyond that there’s another very useful feature in that user interface that really helped me when I was playing 4 sounds at one time on the XGT. If  I was playing a grand piano, organ, strings, and synth sound layered altogether in one program that I created, and I wanted to “solo out” with the grand piano sound in part of the song and not hear the other instruments I had selected, then instead of individually muting the other 3 instrument sounds one at a time by pressing the each volume knobs, all I had to do was press and hold (for a couple seconds) the volume (encoder) knob that corresponded with that grand piano sound.
Muted instrument knobsOnce I pressed and held down the know for the instrument that I want to play by itself, then the other 3 sounds were instantly muted and those knob lights went out. That way I could play a solo part with that grand piano sound alone and then bring in those other parts if and when I wanted them to come back in. When I selected those muted parts again then those specific knob lights were also lit up again. This is a very cool feature and one that I often took advantage of. Very smart engineering and design of the user interface. You can do this with any of the (up to) 4 layered parts.
Basically this 4-part color coded display screen with appropriate color coded knobs can turn, be a push button, and even move/toggle back and forth or from side to side for instant control over features and sounds. All of this including the separate and well placed buttons allow to select functions and features which lets you create and conduct your own orchestra or band.
You are essentially telling your “band or orchestra” members what instrument to play, when to play it, how to play it including volumes, octaves to play in, transposed key if needed, the effects you need to add if needed, and then you play the keys so that your band or orchestra can be heard in a realistic way.


keyboard top
With very functional, well made and intuitively placed physical knobs and buttons that feel good, move good, seem well made, and are easy to see, this XGT user interface will work for you in letting you control the many features and function of this model. It does it in a way that makes it fun and enjoyable to play music instead of always making it a big chore like it can on other brands and models. This is particularly important if you have not had experience with traditional pro stage pianos before. There is an effects section that I have not talked about yet that is also part of the interface user controls which I talk about a bit later.
top panel angledIn my opinion, the Studiologic XGT is easy enough to learn and use that it could easily be a great instrument for someone at home for recreational playing, for a church, for a school, for a home music studio, and not just for pro players on stage or in pro recording studios. It just depends if this type of piano “slab” cabinet format (a portable, metal digital piano with no internal speakers) would work well for your needs. Regardless, this XGT user interface control panel definitely makes it easier to get what you want out of it and play great music.


XGT sound banksThe XGT has a library of 218 sounds and 2 percussion kits as I previously mention. The library of instrument sounds are divided up into 8 sub categories or groups called “sound banks.” There is a button that light up to let you know you are using the sound banks. Within those sound banks are pianos, electric pianos, organs, strings, etc. In each sound bank group there are anywhere from 15 to 50 sounds and you can quickly scroll through those sounds with a knob in the user interface.
strings - sound bankIt’s easy to do and you can “audition” the individual sounds that way by being able to play them individually. You can then assign any of those sounds to an individual program with up to 4 sounds per program as I have already discussed. You can individually adjust the volume, characteristics, and effects of each sound so that you have them the way you want them. Then you save those individual sounds to a program (there are 250 programs available in the XGT) and you can use any of those programs and individual sounds whenever you want to.


favorites - preset soundsTo make life easier in finding the sounds you saved into all those programs, the XGT has a “Favorites” menu that you enter by pressing the light up “favorites button. You can set up your saved sounds and programs in the “favorites” section so that you can quickly and intuitive access them. You can place your saved programs in any order and under any name that you create and then can move from one program to another by way of a turning a knob or even using the triple pedal unit to move from one sound program to another by using your foot and pressing down on a pedal as opposed to using your fingers to turn a knob.
Favorites menuThere are 16 groups designated for the saved programs and the XGT allows you to insert 24 programs per group giving you a total of  384 “Favorite” programs that you have customized and set up in a certain order that meets your musical needs. Now remember, you would have up to 4 instrument sounds  which are in each program. So if you take 4 sounds per program x 384 of your favorite programs , that gives you1,536 possibilities for the sounds that you have set up including layers and splits along with external sounds coming from external devices that become part of the program.
Favorites menuIf that number of programs and combinations of sounds is not enough for you then you are a very high maintenance person:).  However, if there are different people who want of need to play the XGT, then there would be enough “Favorites” custom setups for all of them.
The Favorites library and the individual sound library are accessed by a button clearly spelled out and you use a comfortable and quick turning knob (encoder) to access everything. Again, it’s not the number of individual sounds that an digital piano has, but it is the quality and realism of those sounds. Having 500 to 1000 instruments and special effects in a digital piano might sound impressive, but would you use most of those sounds if they really weren’t that good?
Favorites menusIt’s always the “bread & butter” internal sounds that I care about, which the XGT has. Then I can enhance my music by occasionally bringing in an external sound using USB audio streaming connecting to an external device like an iPad or laptop and using software sounds if needed. But most of the sounds in the XGT are already outstanding as compared to most other digital pianos under $3000. Even the Hammond B3 organ sounds are reproduced in a very convincing way. The “Favorites Menus” let’s me organize everything in an intuitive and convenient way so I can quickly get to the sounds I want or need and have them already set up as layers, splits, combinations, or just one sound at a time, including the effects that I want. The Favorites menu is a great feature to have in this model and it’s something that I would use all the time.


Hammond B3 organSome digital piano controller models from other brands have digital “drawbars/tonebars” that recreate that Hammond organ drawbar experience so that you can make subtle changes to your jazz, rock, or gospel organ sounds and that can be a cool feature. I have played many Hammond B3’s over the years because I also play organ, so I know what that’s like.
The XGT does not have digital or physical drawbars. But that’s OK because it does have an exceptional library of preset Hammond organ sounds that pretty much offer all the authentic B3 organ sounds anyone would need, and they sound great. Those sounds have all the built-in effects like fast and slow Leslie speaker effects, percussive attacks, and so on. Plus, you can customize those organ tones in a number of ways and save them to a “program” for easy access. There are also vintage organ sounds like Farfisa, Viscount, along with some convincing pipe organs, etc.


Orchestral instrument soundsWhen it comes to the instrument sounds, customizing them, setting them up in programs and then saving them to “Favorites” so you can access them quickly, the XGT does an excellent job in that way. This is mostly what “players” care about…great sounds, easy access, setting them up in an intuitive way, and being able to make great music with those sounds. Also, it’s easy and quick to edit those programs, sounds, and favorites so your not spending too much time on “operation” and you’re spending more time playing your music. This is how I felt about the XGT after playing it for many hours over many days.
vintage electric piano soundsAt this point so far I have talked about the primary things in this model that are most important to digital piano shoppers and that is the piano playing experience realism and the instrument sound experience realism. If those two areas are not impressive and practical then the rest of it really doesn’t matter in my opinion. But since those two primary areas are very good, and in some ways exceptional as compared to other brands & models, then the user interface becomes important. In the XGT, the interface and control panel are especially intuitive and overall easy to use.


effects section

So now we move on to the master and insert effects section which take up a relatively large part of the user interface panel. There are 8 effects controller knobs (encoders) which can be turned in either direction to control digital effects features as well as being push knobs to control on/off functions as well selecting different parameters of the effects. The 8 knobs are divided up into sections with 4 of them for master effects and 4 of them for insert effects. There is a master reverb and master delay and also the insert FX A and insert FX B.

Special effectsThe effects section is an essential and integral part of any semi-pro or pro digital piano because the effects will give many instruments the extra organic sound elements they need to sound even more authentic. This is true for acoustic piano sounds, electric pianos, organs, synths, guitars, strings, pads, and most other sounds. Nearly every digital piano out there has some basic effects such as a basic reverb/echo sound and/or chorus for electric pianos, guitar, etc. But just because a digital piano has some effects built-in, that doesn’t mean they sound good.
special effectsThe quality of the built-in effects can also vary quite a bit. There are low quality effects such as low quality reverb, chorus, EQ, etc, in many digital pianos just like there are low quality instrument sounds. Low quality effects makes the instruments sound much more artificial and more like toys. The XGT effects are stage & recording studio quality and you won’t be disappointed. I certainly was impressed with them and I felt like they added a lot to the music listening and performing experience of the XGT, and they were easy to use and control.
Effects sectionThere are 35 total separate instrument effects in the XGT divided into 4 sections. I already mentioned those 4 sections earlier. You would have 8 total knobs (encoders) to control these different instrument effects with 1 row of 4 knobs on top and another row of 4 knobs underneath. The top row of encoder knobs select the type of effect as well increasing or decreasing the amount of that effect you want along with turning them on or off. The bottom knobs select the parameters of each effect and the intensity of those parameters. There are 3 effect parameters per main effect. There are 3 light indicators showing which parameter is being used. When the top encoder knobs are lit up then that’s when you know that effect is on and being applied to the sounds you have in your programs.
Reverb effectsThere are 3 parameters per effect that you can control and you know which parameter you are controlling because you can select them individually by pressing the corresponding controller encoder knob and then a led light under each bottom row knob will light up and show you which parameter has been selected. So you can easily see what’s going on even in a darker area. This is a very convenient feature and they work well. The knobs feel good and turn easy and selecting the amount of each parameter you need simply requires you to turn the knob one way of the other. Very easy.
Vocal reverb effectsThere are also 14 special vocal effects (in the reverb effects section) that come up when you plug a microphone into the XGT. You can plug in up to 4 separate mics and control them independently along with those vocal effects. These effects include pro vocal reverbs and delays. I will talk more about inserting microphones a bit later, but the effects for the microphones are really good and if you are going to be doing and singing then those special effects are essential to your singing. The vocal reverb and delay effects are separate and distinct from the instrument reverb and delay effects and only work when a mic is plugged in.
Instrument EQ effectsThere is also separate EQ controls for each of the 4 instrument zones per program so that you can add more or less bass, more or less mid-range, more or less treble to each sound. You can control these different things quickly and efficiently and it is easy to do. Customizable, quality EQ settings for each instrument is also essential for adding to the realism of the instrumentals. For vocal EQ you would use the master EQ section for the entire instrument.
Once you select the type of effect you want to have for instruments or vocals, then you can independently control the volume of each effect by turning the appropriate knob or turn each effect on or off with a simple push of a knob. The effects will apply to all internal sounds and all external MIDI sounds you put through the XGT. It’s great to be able to apply the internal effects to any external sound you want to bring into the XGT.
FX AThe effects are excellent, very pro quality for those people who need something “better” and each parameter of an effect can also be tweaked and controlled by the additional encoder knobs. This gives you the ability to customize the sounds you are using and then save all those effects into your instrument sound programs and they will be recalled instantly the next time you play those sounds.
Studiologic definitely did not overlook the effects sections in the XGT and they put in some high quality technology which is impressive and helps recreate all those studio effects that are used with grand pianos, electric pianos, organs, orchestral, vintage synth sounds, guitars, etc. The user controls are intuitive, they are also color coded which is very cool so that you can see which instrument sounds line up with their specific effects which lets you know what instrument effect you are adjusting.
color coded control panelColor coded and easy to see controls is another thing the XGT does well and they did the color coding thing not only with the instruments, as I mentioned earlier in this review, but also with this effects section. This means that when you want to add effects to an instrument within a program, then that instrument is color coded and coordinates with the same color in the effects section. So that way you know which sound you are adding the effects to. Everything is color coded. When all these features become easier to handle and manipulate as they are in the XGT, you will tend to use them more often and take advantage of what they can do…and all that works very well in this Studiologic model.


Pitch bend and modulation wheelsA couple of other effects controls that many stage digital pianos and keyboards have on them are called the modulation and pitch bend effects wheels. Different brands offer different configurations and designs when it comes to the physical parts that control these effects. They can either be 2 movable “wheels” on the left side of the keys, above the keys, or next to them or they can be in one movable controller that can do both effects within one controller, sometimes called a joystick. This image here is an example of what you might normally find on a stage type/recording studio digital piano or keyboard. The XGT does not have this type of wheel controller.
Studiologic Pitch bend & Modulation sticksOn the XGT, the Studiologic company put in 2 convenient controllers which they call “sticks.” They are independent of each other, small, and easily movable silver sticks with one of them able to move in any direction up or down and side to side or in circles. That one is called stick #1 and it can be assigned with 2 functions (X & Y) such as pitch bend and modulation in one controller. The controller stick always settles back into the center when it is not being used.
The other stick is called stick #2 and it moves side to side and stays wherever you put it. This means that if you need some modulation all the time then you can just put that controller stick in any position and it will stay there until you want it in the off position.
controller stick functionsBoth sticks are assignable from the main menu display to control different effects such as modulation (vibrato), pitch bend, enabling different FX effects, etc. These sticks are located all the way to the far left side of the piano where they are out of the way but yet in a good position. They are not big and bulky like other controllers (wheels) can be and they look good too. Each stick is easy to use and comfortable to hold and control. I personally like their size and feel and they are a very nice alternative to the bigger bulkier wheels or joysticks that you would likely find on other brands and models.


connectivity ports
Being able to connect external devices to a digital piano can be very important, especially when it comes to a stage or recording studio digital piano. However, since this model XGT is also a great choice for recreational home use, connectivity options are also important in a digital piano like this one for a variety of reasons.
The XGT connectors are all located on the back of the piano. These connector ports include a standard USB to host port, standard MIDI in & out, stereo headphone port, two 1/4″ audio outputs, four 1/4″ audio inputs, and three pedal inputs,  These different connector ports are fairly self-explanatory for people who have used or had these features before.
pedal settingsHaving three pedal options allows you to control 3 functions with the triple pedal unit that is included with the XGT, and those functions can be the traditional piano pedals or you can also assign different functions to that triple pedal unit in the Global settings feature. Then on top of that you can connect two single pedals to the XGT to control other functions such as expression or other pedal setups that you can do.  In that way you have a variety of functions you can quickly control with your pedals and its especially helpful when playing live on stage, in a recording home or pro recording studio, etc.
Microphone inputs and controlThe TS/mono audio inputs are for controlling and mixing microphones or external electronic instruments or recording devices that you want to connect into the XGT. If you wanted to do something fairly simple and you had a few people who you wanted to do vocals with you, then you can connect up to 4 microphones to the XGT and control each microphone independently for individual volumes and effects so that each voice blends together perfectly while you play the XGT live.
audio input settingsEssentially you have a 4-channel audio mixer built into the XGT for complete control as well as being able to quickly mute any of those audio channels when you don’t need them. You can set up the four audio inputs in any digital configuration including 2 mono/1 stereo, 4 mono, 2 stereo, etc. It’s easy to do those setups and helps give you the type of audio preproduction that you need and to be able to mix those signals together to achieve the desired audio outcome for the devices you are using and controlling within the XGT. There are also audio input digital EQ controls for quick changes on the EQ settings for any audio device, mic, etc that you connect to the XGT.
audio input zone EQ controlThe connector array on the back is clearly labeled in small white lettering on the top back of the XGT. The names of those connectors are written right above where they are located as well as on the top of the XGT so that you can easily figure out where each of those jacks and ports are located for quick access. This is very helpful because I have run into brands and models where you don’t know where they are located because there is no indication of their position or you cannot see them clearly.
power supply port & on/off switchThe power button and power supply input are within the lineup of connectors in the back of the XGT near the center, so they are within easy reach of everything. Having it that way is very helpful instead of  the power supply and power buttons being on the far left or right side of the back of the piano like some other models do. However, I wish the stereo headphone jack was on the front left of the XGT for easier access and I would have preferred it that way. It’s on the back and unfortunately that’s fairly typical. I suppose it saves the company a bit of money to have it on the back with the rest of the connectors.


Global settings - transposeMost stage and other portable digital pianos have Global settings. Global setting have useful functions that apply to all sounds on the piano rather to specific sounds, programs, or favorites. As an example if you want to modulate your key and transpose your musical, then you can go into the Global settings section by pressing the settings button and the first function you will see is “transpose.”
When you want to transpose your song then you turn the main function knob slightly to the left or right and it will increase or decrease the transposed key by 1/2 step at a time. It’s easy to do and will stay in that key until you transpose it again. You can also transition from one key to the next while playing, and when you change keys your instrument sounds will not move to the next key when you are holding down those notes until you “re-key” those sounds.
global settings - transposeIn other words the transpose function will allow you to move from one key to the next in a very smooth way without having any of the sounds cut out. You can always see what transposed key you are in because in the main home screen the transposed key will show up in a smaller red row at the top of the home screen. This is very useful to know where you are at if you have transposed the music you are playing.
As an example, the transposed key will read out +2 or +3, or -3 depending on what you have selected. This would mean how many half steps you have moved from your original key. If you want to go back to your original key then you simply turn the knob so the transpose function is at zero (0).
Global settings - velocity curve & keyboard sensitivityOther Global functions would include setting up your assignable pedals, sticks, MIDI channels, after-touch, velocity curve, keyboard sensitivity, etc. These settings can be very useful, especially the velocity curve depending on which instruments or sounds you are playing. For instance, sometimes you would want a sound like a synth or trumpet, or electric guitar to respond more quickly when you touch the keys than you would for piano and other instruments. So then you set the velocity curve on soft to play certain sounds more accurately.

After-touch effectAfter-touch control is also a big deal to some players out there because you can add vibrato to any sound by simply pressing down any key harder after you have already pushed down a key to the bottom. Once the key is depressed all the way down, then you hold it there and press again harder. When you do this it triggers a vibrato effect for the sound on that key. such as what you might want to do for a violin, guitar, or other instruments. Typically it’s the pro stage digital pianos and keyboards that would have “after-touch.”
Master EQ settingsThere is also a separate global 4-band master EQ feature that allows you to quickly adjust the EQ levels for the entire instrument. You use the 4 encoder knobs to the left of the display screen to adjust each of the EQ bands and you can also adjust the master reverb and master delay intensity for the piano as well The master EQ is easy to use and right at your fingertips for quick overall adjustments when you need it. There are other useful Global features and settings depending on what you need for the music you are playing.


Final Thoughts


cabinet end view

The XGT not only has a good looking control panel and layout but as I mentioned already, it is user friendly and intuitive to control once you have don’t it a few times. The cabinet (case) finish on the XGT is in slightly textured matte black and feels good to the touch. The designer wooden sides on the XGT made out of ash wood really makes this model look elegant and gives it some “class” in my opinion. The special design allows you to see real wood grain and the corners of those sounds are rounded a bit and the exterior is slightly beveled and looks great.

Numa X display screen - loadingI really like that the cabinet (case) is not just a plain black slab. The controls, knobs, and buttons have that organic retro feel to them as opposed to some that are much more contemporary with imbedded touch sensor buttons, touchscreens, or a combination of all three. So when it comes to a control panel user interface and layout, the XGT is comfortable to use and fairly easy to figure out, and I really like that 4-part color screen with corresponding color control knobs for the instrument sounds and effects section. The connectivity is there and pretty much what most people would need.
The measurements of this digital piano are approximately 51″ x 12″ and the weight is about 49 lbs, so it certainly is not light. There are a number of pro stage digital pianos that are right around the same weight, some that are a lower 40 lbs or less, and some a bit heavier than 50 lbs. But given the XGT’s all metal construction along with feeling well put together, I am not surprised by its weight. At least it’s not 75 lbs as some others are! But weight is always a consideration if you need to move it often.
Studiologic 2 year parts, 1 year labor factory warrantyThe Studiologic digital pianos have a factory warranty of 2 years parts and 1 year labor. That warranty is OK but not great. There are some factory warranties for other brands that have a shorter warranty time than the Studiologic models and some that have longer warranties. Stage or pro studio digital pianos like this one typically have shorter warranties because the manufacturer knows (because of experience) that pro players and studios will be rougher and harder on these models and give them more wear and tear, dropping them, banging them up, etc. If this model and others like it was strictly a “home studio”, or home portable piano in general, then the warranty would likely be noticeably longer.
anything missing?There are a few things this model does not have that I would have liked. It doesn’t have Bluetooth wireless MIDI or audio streaming, no recording of any kind, no USB thumb-drive slot for general storage which is mostly used for saving or loading songs, and this model does not have it. There are no drum rhythm patterns, there is not 500 or more internal sounds, and there are no digital drawbars for Hammond style organ sound adjustments. But what it does have is very impressive and will serve most people’s musical needs quite well.
USB MIDI controller settingsIf you want the XGT to do “more” then you can always use an iPad or computer for connecting with external instrument sounds, percussion, drum rhythms, etc. You can also connect with a desktop and use the Studiologic proprietary Numa Manager controller app for loading in new sounds to the XGT (which is very cool) as well as using that app to further control and manipulate your saved programs as well as do firmware updates when needed and available. So even those aspects of controlling and using the XGT externally are there and available which opens up many more possibilities if you need them.
Music holder restThis Numa X Piano GT by Studiologic checks all the boxes for me when it comes to a home studio, pro recording studio, and stage digital piano, especially in this price range under $2000. Plus there are 3 optional accessory pieces (for an extra cost) you can add to the XGT which include a magnetic music stand, a magnetic computer plate, and a carrying case. The magnetic accessories are definitely useful and Studiologic provided an attractive copper color magnetic strip on the back of the XGT so that either the music stand and/or computer stand can be easily attached. They look cool and work good.
XGT key actionThe only other things this Studiologic digital piano could have done that I would have wanted would have been good a internal speaker system, wav and MP3 recording capability, a thumb-drive port to handle storage, and Bluetooth Wireless MIDI & Audio, as I already mentioned. But those additional feature would definitely add more cost to the XGT. Beyond that I would have liked if the key action was a lot less “thumpy” so that the key action noise would not be as noticeable. Also would have preferred if the black keys were a little less heavy to better match the white keys as far as weight. Overall the key action is enjoyable to play but those are improvements that would be good to have.
XGT control panel interfaceIt’s easy to “pick apart” a digital piano because being “picky” is fairly easy if you try. But…given this model does what it does, and works the way it works, and looks the way it looks…it’s a “slam-dunk” for me as far as recommending it to anyone who wants great sounds, great control, and a piano style key action that is actually much better than I thought it would be, and far beyond the average portable studio digital piano. In fact, I think the XGT is underpriced for what it is and should be more like $2499 instead of $1999. I really enjoyed my playing experience with it and it was exciting for me that I could make and play inspiring music I was hoping I could do on this model. I would definitely put it in a “premium” category with the very cool features that it has.
XGT wooden side panelI also asked a few other pro piano players that I know to try out the XGT and they felt the same way, especially when playing the acoustic grand and vintage electric piano sounds…they thought those sound were really good and very expressive. So, there it is, a fairly exhaustive review of the Studiologic XGT. There are a few “controller” aspects of this model I did not cover and that’s because my brain was hurting after covering this much detail. If you want to know more then look at the specs and try it out yourself if you can find one. But finding one may be difficult because they seem to be in short supply…perhaps due to their popularity. Or better yet…buy one because I don’t believe you will be disappointed. ??

  1. Hi, thank you for this big review of the xgt that i'm actually waiting. The only thing that i'm afraid is the sound of the key. You say that the Keys are noisy. However, in other forums I had read that this was not the case. With your review i'm really afraid because the silent is important for me. Do you know witch keyboard like xgt is silent ? Thank you.
