The Korg G1 (aka: G1B Air) comes in 3 cabinet colors including matte black, darker matte brown, and matte white. The G1 Air also has a newly redesigned cabinet with the addition of a “privacy panel” on the back of the cabinet so that you cannot “see through it” any longer. On the previous model there was no privacy panel so it was completely open in the back. The addition of this privacy panel gives this model an upgraded appearance and now it looks more elegant and finished as you can see on the top 2 photos of the piano in this review. The rest of the piano including all digital features functions, internal speaker system, etc, is still the same. However, Korg did improved the fit & finish on these models along with some internal improvements in the new version as compared to the previous version.
Although the model number G1 Air has not changed on the piano itself, the “official” Korg model number for this new version is now called G1B Air, but I will continue to refer to it as “G1 Air.” The G1 Air is without question one of the best selling, most popular furniture cabinet digital pianos under $2000. After personally playing and analyzing this the G1 Air, in my opinion Korg has managed to
surpass some of the other top name brands in this price range for a home digital piano including Roland, Yamaha, and Kawai. Korg pianos and keyboards have always been very popular with
pro players around the world and over the past 10 years they having a positive growing reputation with families and piano students.
But this brand is still not as well known as Yamaha, Casio, Kawai, and Roland for home digital pianos. However, Korg takes its advanced digital piano technology from their higher priced pro digital stage pianos that sell for up to $4000 and they put some of that advanced sound and key action technology in their home digital piano line and that is what makes Korg so good with regard to home digital pianos…they know what they are doing and they do it well.
KEY ACTION
So what are the things that makes the Korg G1 Air so good and why do I like it? First of all the piano key action is amazing in my opinion but that should come as no surprise to me because it is the same key action that Korg uses for their top of the line professional Kronos stage digital pianos and I have played those instruments many times. A key action needs to be properly weighted, graded, and responsive not only in touch but how it triggers the piano sound from a light gentle touch to a hard touch, and for a fast movement of your fingers across the keys. As I have talked about in my other reviews, the quality and movement of the key action is 1st and foremost when shopping for and considering a digital piano.
The Korg RH3 key action is outstanding in just about every way, but especially in this price range, and the RH3 key action does not feel like any other brand of home digital piano under $2000. It’s very unique in that it has a natural, organic piano feel to it and in my opinion it is very responsive regardless of the type of music you are playing or whether you are a beginner or very advanced player. You can really pound on this key action or play it lightly with subtle finger movements and the G3 Air responds accordingly like a real quality acoustic piano does offering lots of expression and great balanced weight on each each key so that you can really connect the keys you are playing to the music you are wanting to make. In other words you can put a lot of feeling into your music and this RH3 key action will keep up with you and not disappoint.
I would consider the touch weight on this key action to be “medium” meaning not too firm and definitely not light. When you press down on the keys it feels like you are pressing down on acoustic piano keys in terms of key weight whether they be white or black keys.
Also, just like on regular acoustic upright and grand pianos, the white key tops are made of a synthetic gloss white acrylic and the black keytops have a matte black finish on them which is nice so that you could more easily transition from this digital piano to a real acoustic piano without noticing much of a difference at all, especially when comparing the G1 Air to a fine upright acoustic piano.
Within the last 10 years or so a few digital piano manufacturers thought it would be a good idea to try to create a synthetic version of those organic materials and put it on their digital piano keys. Depending on the proprietary chemical makeup of this “synthetic” material, the result in the beginning was pretty bad and the synthetic material did not hold up well at all. Although it has gotten much better, it is still synthetic and in reality real piano keys on acoustic pianos don’t feel that way.
So when it comes to the keytops of the Korg G1 Air, the keys look and feel like real acoustic piano keys and are not synthetic versions of keys that were out decades ago. In reality, you can play on any of the keys of the major brands and be fine, but the synthetic nature of the keytops is ultimately a mute point in my opinion when it comes to playing a piano. Some people may say that they think slick white keytops are “plasticky feeling.” But then you need to consider the fact that is how real acoustic piano keytops feel…the same way as the Korg RH3 key action. It really just depends on what’s important to you. The final thing I will mention about key action, and in this case I mean any key action on any digital piano, is the build quality and the noise level of the keys when they move.
The Korg RH3 key action has been out for many years and is nearly “bullet proof” as far as durability based on all my experience with this particular RH3 action. It is solid with very little lateral movement or wiggle, all 88 keys are well aligned and mechanically move up and down uniformly, and just as importantly, this is a (relatively) quiet key action when it comes to the keys moving up and down. On every digital piano brand and model there is mechanical key noise and depending on the brand and model and that key movement noise can be very loud and irritating.
This can be especially noticeable when playing the piano while wearing stereo headphones when the only thing a person can hear (other than the player wearing the headphones), is the sound of the keys going up and down. Sometimes the noise happens when the keys go down and sometimes it’s when the keys come back up. I can tell you from experience that the G1 Air key action has quieter keys regardless of what direction they are moving or how hard you are playing the keys.
However, there will always be some key noise because keys are mechanical just as they are in real pianos. But it’s really all about how the key action is made with as much key noise reduction as possible in this piano, and the developers at Korg knew what they were doing because this is right at the top when it comes to quieter key actions in the digital piano business. My hat is definitely off to Korg on this one ??
PIANO SOUND REALISM
The next important thing that people are looking for is accurate, natural piano sound…but what does that mean? Piano sound can vary in a number of way from one piano to another, one brand to another, and one model to another when it comes to real acoustic pianos and how they sound. They can have a bright, medium bright, more mellow, very mellow or delicate tone with dynamic tonal expression, or without dynamic tonal expression. The main aspect and goal of a great piano sound is…can it play music in a very delicate and mellow way all the way to big, bold, and
dynamic tone while offering a great amount of
musical color and expression all in one piano? The answer is “YES” but as long as it is a great grand piano such as the ones played in symphony concert halls of by famous jazz or pop piano players such as Billy Joel, Elton John, Duke Ellington, Oscar Peterson, etc.
Ultimately, music is about passion & expression and the piano sound being able to come out of (in this case) a digital piano with a wide range of musical colors depending on how hard you strike the key, how many keys are being played simultaneously, coupled with using the damper-sustain pedal and how all that interacts together.
The Korg G1 Air really surprised me with all of the musical colors and dynamic tonal range that it has. It’s one thing to have a really good key action but it’s an entirely different thing to also have a satisfying acoustic piano sound experience and the G1 Air delivers on that point too. To help achieve a wider dynamic tonal range you would adjust key touch curve and brilliance/brightness on the control panel to give you more “expression” in the grand piano sounds.
Almost all of the digital piano companies out there claim to copy or sample a full grand piano sound and put it into their digital pianos…but that is easier said than done. Copying or sampling a piano sound is just the first step of the process, but then that digital piano company needs to have copied that sound from a quality grand piano with the proper microphones, the proper technology, and then put all that into their digital system which can then hopefully correctly translate it into the digital piano so when you play it then that sound comes out sounding
real and natural rather than fake and artificial. In my opinion the Korg G1 Air gets extremely close to sounding like it is
not a digital piano but instead a real acoustic piano, and that is really hard to do, especially in this price range under $2000.
The G1 Air has 7 acoustic multi-sampled piano sounds which are accessed on the control panel with a row of three buttons. The first button accesses what Korg calls “
G” grand piano sounds and the “G” stands for a
German Steinway grand piano. Each button has 3 variations of piano so every time you press that button the sound advances to the next piano sound in that sound bank. The next Button is the “
A” grand piano sounds which stand for an
Austrian Grand Piano otherwise known as Bosendorfer and there are variations within that button of the Bosendorfer grand piano sound that are different from each other.
The next and last piano button is the “J” grand piano sounds with the “J” standing for Japanese grand piano and in this case is a Yamaha concert grand piano. Since Korg does not build acoustic pianos then they were free to choose any of the famous grand pianos out there to be included in the G1 Air instead of being limited like other digital piano companies are because they may not want a competitive acoustic piano sound in their digital piano. For instance, you would never see a Yamaha grand piano sound in a Kawai digital piano because those two companies are fierce competitors in the acoustic piano world.
Likewise, you would never see a Steinway grand piano sound in a Yamaha digital piano because those two companies are fierce competitors in the acoustic piano world. Korg does not have that issue because as I said, they don’t build acoustic pianos so they have more freedom to use different high quality acoustic piano samples in their digital pianos.
Since Korg does not build real acoustic pianos then how come their piano sounds in the G1 Air are so realistic with so much tonal color and expression which all great pianists seek when shopping for a piano? We’ll, just because you don’t build real acoustic pianos does not mean you don’t know how they work and what goes into them. Korg has an experienced staff of professional pianists along with outside professional tech support from top rated concert piano technicians/tuners who are advisers to Korg piano division. Beyond that, Korg has digital music technology that is so advanced that they have won many awards throughout the world over the years from big name industry leaders for their advanced proprietary sound technology which they also use in their stage pianos.
Given Korg’s expertise in this area and my long time experience playing many of their previous stage and home digital pianos, I still was blown away by how much “presence” the G1 Air had when playing it.
I have played it in a small room, a big, room, and a really big room and it did a excellent job in all venues. But when you put it in a regular size room in your home, studio, etc, then you can really hear it come alive when playing on it. The
stereo tonal expression of those grand piano sounds are all so different with the German Steinway stereo sound being mellow when playing more lightly but also big & bold when really putting some force into the keys (Billy Joel plays Steinway grand pianos). The Austrian Bosendorfer stereo sound is more delicate but at the same time the bass frequencies really come through to make it a big resonate tone when putting some energy into your playing…really a beautiful sound (great for classical music). Finally, the Japanese Yamaha concert grand stereo sound is brighter and more distinct and the clarity cuts through with a more metallic tone just like Yamaha grand pianos can be (a great pop piano sound – Elton John is famous for being a Yamaha grand piano artist), but there is still a nice bold, bassy tone as well.
Then when you mix two different stereo acoustic piano tones together which you can do on this piano, then you can have the best of both worlds in terms of the personality and character of that mixed stereo piano sound.As an example you can combine Austrian Bosendorfer with German Steinway or Japanese Yamaha with Austrian Bosendorfer and you can select which version of each piano to combine with the other one. When you make those combinations it really is like hearing both pianos playing at the same time mixing their unique stereo tonal qualities qualities together in a way I have not heard before on any digital piano in this price range.
I can tell you by experience as a long time piano teacher and pro musician that different people like the sound of different pianos.A piano sound that I may like, another person may not personally like that sound as much…and that’s OK because we all have different ears. The point is that at least on this Korg G1 Air piano you have 7 different acoustic piano tones coming from 3 distinct grand pianos to choose from plus all the combinations you can get when mixing them so you are likely to find one or more piano sounds that really
speak to you.
When it comes to a natural, organic acoustic piano sound with lots of dynamic tonal color in this price range, this G1 Air is pretty amazing, and if it impresses me (which it does), it should also impress you. ??
POLYPHONY
One thing that is especially important for me to mention here is the polyphony specification of the G1 Air. Polyphony is a number that a lot of digital piano shoppers don’t really understand at all or maybe they think they understand it but they really don’t. Either way, the polyphony number (amount of maximum notes that can be heard playing simultaneously) of a digital piano can play an important part in the ability of the piano to play the piano and instrument sounds in a way that sound good and natural.
A few decades ago it was not uncommon to see digital pianos have 12-note polyphony, then 24 note, 32-note, and then as the years went by and digital piano technology got better you would 48-note, 64-note, 92-note, 128-note, and now today it is not uncommon to see 256-note polyphony. However, here’s where it gets complicated; polyphony is rated in mono, not stereo. Piano sounds in older digital pianos could only be heard in mono, not stereo. But for last last number of years piano sounds in most good digital pianos are recorded and heard in stereo which is great because they sound better that way.
However, just because they are in stereo does not mean that’s the only thing which has changed.Some of those stereo piano (and instrumental sounds such as string symphonies, etc) are so complex that they include more organic elements in the piano sound which makes them sound more natural such as string resonance, sympathetic vibrations, overtones, and other natural sound recreations through new digital piano technology.
Some of the non-acoustic piano sounds such as electric pianos, guitars, etc are normally recorded in mono, not stereo. Then there is something called “dynamic voice allocation” which allows the computer chip to allocate certain notes that you are playing to remain being heard even when you are supposedly over the maximum notes of polyphony. Are you getting confused yet? Don’t worry….you should be.
Here’s the bottom line concerning polyphony; the way I judge a digital piano’s ability to have enough polyphony is to play the best stereo piano sound in that digital piano using complex classical music playing as many notes as I can while using the damper-sustain pedal. Trying this method will quickly tell you if you can hear any detectable “note drop-out” while playing the digital piano. With a low polyphony number in other digital piano brands & models, when you play complex music with lots of notes using lots of damper-sustain pedal, you normally
will hear sustained notes
abruptly stop playing, even if you have those keys pressed down. In other words you just won’t hear them anymore because you have out-played the polyphony. The computer chip just won’t play any more notes until you release most of the other notes being played along with releasing the damper pedal (which resets the polyphony) so that you can play new notes and hear them. Yikes…sounds crazy but that’s the way it works!
KORG G1 AIR POLYPHONY TEST
So why am I going into so much detail about polyphony here? It’s because the Korg G1 Air polyphony specification says 120-note maximum polyphony which seems low by today’s standards compared with other digital piano manufacturers having 128-note polyphony, 192-note polyphony, and 256-note polyphony.So people would normally think
more is better and
less could cause playing problems, right? No, actually not in the case of this G1 Air because of proprietary piano sound sampling technology.
The bottom line is this; if you play the piano well and try to out-play the polyphony on the G1 Air like I did and you cannot hear any note-drop-out even while playing full glissandos (when all keys are played by running all of the keys from low end to high end) and/or playing arpeggios while holding down the damper/sustain pedal, then the 120 note polyphony number on this piano is not an issue at all. It’s really all about what you actually hear when playing this piano and not what the polyphony specification might suggest.
As a matter of fact, the Korg G1 Air sounds like is has almost unlimited polyphony because of how good the sound sample and electronic technology is without note any drop-out interruptions no matter how I played it. When I layered (mixed) a stereo symphony strings on top of the piano sound then occasionally I would hear a few notes drop out when I was playing a many notes while holding the damper pedal, but they were the string sounds dropping out and it was quite subtle due to the dynamic voice allocation system that Korg employs. I’ve had that same thing happen on digital pianos with a higher polyphony specification.
Plus there are few people, other than myself, who would drive a digital piano that hard to try to get note drop-out. So under normal playing situations, even when layering two sounds together (piano + ?) and using sustain pedal, you won’t hear note drop-out on this G1 Air and that’s what polyphony is really all about…being able to play music even at advanced levels and have the piano sound react as it would on a good acoustic piano and it definitely does that with the G1 Air.
So just don’t get hung up on polyphony specs…it’s really all about what it’s like in “real life” and I can tell you by experience the G1 Air can keep up with any of its competition, even in much higher price ranges for actual piano playing when it comes to the polyphony issue.
PEDALS
OK…so what is next? It’s got to be the pedals. There are 3 pedals that come with the G1 Air and they play like a real piano. All 3 pedals will do what they are designed to do including soft, sostentuto, and damper-sustain.Since the damper-sustain pedal (the right pedal) is by far the most important pedal as it is used probably 99% of the time, then that’s the one I want to talk about. On the Korg G1 Air, all of the pedals including the damper-sustain pedal have a good amount of resistance when pressing down the pedals and the pedaling mechanism overall is
very quiet unlike some other digital pianos which have noisy pedal movement.
In other words they don’t feel like cheap keyboard pedals and other digital pianos that have pedals that are much too light and noisy and offer little resistance when you press them down which is not good. So the G1 Air pedals definitely feel more realistic. The damper-sustain pedal part of the 3-pedals is important because it controls how much sustain is coming from the notes you are playing. The damper pedal needs to offer the half-damper mode which allows for a variable amount of sustain instead of just on & off.
Fortunately the G1 Air does offer this feature and it works fine and allows you to do your pedaling as you would on a grand piano. Speaking of grand piano, when you press down your damper-sustain pedal while playing some notes in the middle of the keyboard for example, the notes should sustain over a period of time before they naturally fade out until you cannot hear them.
On a regular grand or tall upright piano when playing notes in the middle of the keyboard and using your sustain pedal, the amount of time a note takes to fully fade away with natural volume decay time as well is about 25 seconds or more depending on the size of the acoustic piano. The bigger the acoustic piano, the longer the strings and the longer the decay/sustain time will be.
That’s why when you hear a ginormous 9′ grand piano sound, it’s so beautiful because there is so much tone and sustain going on in the piano. Long decay/sustain time is very important in creating beautiful, resonate music with the piano strings vibrating and resonating together over time.
OK, now that you know all of this detail about pedal decay/sustain time and sustained note volume, here’s why I brought it up; many digital pianos have very little pedal decay-sustain time for their piano sounds.In fact some digital pianos fade out in less than 6 seconds of time, which is terrible. One of the big reasons for such poor pedal sustain is because they use a cheaper piano sound chip with a small amount memory that cannot hold a note for more than a few seconds.
Other digital piano are much better and can go up to 10-15 seconds of time which is fine if you are a beginner or low intermediate player. But if you are a better player or even very an advanced player you definitely want the digital piano to have the sustained piano sound like a real piano where it’s long and beautifully resonate. The Korg G1 Air has an incredible amount of pedal decay/sustain time across all 88 notes and way more than I thought it could have. In fact in the middle of the keyboard the decay/sustain time with sustained note volume was a whopping 25 seconds until it fully faded away.
It was even a higher amount of time on the bass notes (as it should be) and a slighter lower amount of time on the treble notes (as it should be). In other words, with regard to piano decay/sustain time, this G1 Air outperforms any other furniture cabinet digital piano under $2000 that I know of in this way.
I was very impressed that it could keep up with the demands I put on it when it came to sounding beautiful regardless of whether I wanted quick staccato notes or long resonate sustained notes over time. I am impressed with the Korg company for being able to accomplish this task particularly in this price range.
There are some digital pianos whose instrumental sounds really come out sounding like toy instruments and it’s easy to hear that as compared to this Korg G1 Air.These extra instrument sounds in the G1 Air that I mentioned really are at a pro level in quality and realism especially the electric piano sounds, strings, and the organs including pop, jazz, classical, and church. Korg did a great job including quality sounds instead of just quantity with low quality. However, there is no brass, woodwind, synthesizer, and or other similar sounds in this model so if you think you want those tones for some reason then the G1 Air does not have them.
For the majority of piano shoppers out there I don’t think this is an issue at all. The control/button panel itself is a polished black piece of Plexiglas with smaller all matte black buttons which have a built-in red light when the button is selected (very useful) and also a simple, easy-to-use master volume knob on the left side of that panel which all help give the the G1 Air a bit of class along with it being more minimalist in appearance without having too many buttons. I did want to mention something that bothered me just a bit. When you press any button or function on the piano, if you were playing a previous sound and wanted to switch sounds in mid-stream or use an editing function to make a change to the sound, the previous sound immediately cuts off and stops playing.
In other words, you cannot manipulate sounds in real time as your are playing your song. You basically have to set up the instrument sound the way you want and then play your song. I am not fond of this system and in fact most digital pianos don’t have this limitation.
The only other brand I know that does this is Roland on all their new digital pianos over $2000, but that limitation is only on their piano sounds and not on every button and every sound. So I am disappointed in the G1 Air concerning this limitation and hope that Korg can improve upon this in the near future.
Perhaps it is an issue because of this new piano technology they are using to get their new piano sounds…I don’t know. Personally I do not think that most people will care about this “deficiency.” I am just a bit more picky than most people when it comes to digital pianos. However, I think most peoplecan be happy picking your sound, function, feature, etc and just playing your song and then change settings in-between songs. The G1 Air can do that well and I think that’s what most people tend to do and won’t be bothered by this limitation at all.
On the control panel there are 2 more buttons next to the instrument sound buttons called favorite and split.The split button allows you to put one bass instrument sound on the left hand and one on the right hand to be played independently but simultaneously, such as a string bass player on the left and a piano on the right like a jazz trio might do, minus any drums because the G1 Air does not have any percussion/drum patterns in it other than a preset bass/cymbal sound which is nice. You can determine where the left and right hand separate by holding down the key on the keyboard where you want the separation to happen…easy to do.
Also, unlike other digital pianos including the Korg C1 model below the G1 where the right hand is always the piano sound in the split function and can never change, on the G1 you can assign any instrument sound of the G1 (electric piano, strings, etc) to the right hand melody while having the bass sound (bass guitar or string bass) assigned to the left hand.Within the “others” button there are a lot of sounds that you need to scroll through to find in that button so it does take time to do that. It’s not the best way to find sounds as I would have preferred more sound buttons for direct access. But, you can save your favorite sound in the others button (strings, organ, electric piano, etc) by actually loading it into the favorites button for instant recall.
That works good and if you have a favorite “layered or mixed” combination of two sounds that you use often then you can choose to save that “layered” sounds as well for instant recall. When it comes to the internal sound library in the G1, if you want to layer (mix) any two sounds together to play at the same time, you just press two sound buttons together at the same time and you’ll get an instant layer. One quick comment worth mentioning is that the function button features are not convenient to use as well as being somewhat cryptic to find.
You have to scroll through the function button and the editing features inside to find what you are looking for based on a chart in the owners manual. There is no direct access button or easier way of selecting the function. For instance, if you want to to transpose the key you need to go into the function button and then scroll through a few settings until the the transpose mode comes up and then you can select a key you want to be in.
A couple other digital pianos, particularly the newer Casio AP-470 now offers an iPad/Android app so that you can easily and intuitively control these features with a proprietary control app from your device color touch screen…it makes the whole thing so much easier, assuming you have an external device to do that.
Otherwise on the G1 Air you need to rely on the piano operating system to get around and through the functions which is a bit more challenging, but it is certainly doable on the G1 Air and not difficult. I am hoping that maybe Korg can come out with a device controller app one day for the G1 Air which would make things easier to navigate, especially in the editing section. But again, I don’t think most people care about using a controller app and will just use the buttons on the control panel.
EDITING MODE TO SAVE SETUP
ith regard to using the editing features & setups, it is worth mentioning that Korg implemented a function in the editing mode that saves the last set-up that you used just before you turn off the piano. Then when you power up the piano next time you want to play, that previous set-up instantly comes back on which can be a good thing if you want to use that setting often when you play the G1 Air.
So for instance, if you want the “Viennese Bosendorfer” 9′ concert grand piano sound along with your own reverb, brilliance, and touch settings to come on instantly the next time you power up the piano, you just make sure your save function for your setups is on (in the piano menu) and then the G1 Air will remember what you last were using and bring it up again when you turn on the piano so you don’t have to start from scratch. That’s pretty cool.
RECORDING & PLAYBACK FEATURES
On the right side of the control panel there are some other buttons which control the digital metronome and the 2-track (2-part) MIDI recorder. The MIDI recorder is useful, especially for students because it allows you record your left and right hand independent of each other and then play them back that way so you can hear how your right and left hand parts are doing by listening to them apart from each other. Then when you have done that you can play back both recorded parts at the same time to hear how the song is doing and to see if you need to make improvements. You can use the digital metronome and set it
to any time signature and tempo you want which helps with rhythm and timing training while you are learning your songs.
In the recorder section you are able to play and save up to whopping 99 individual songs in the the piano including 999 measures (or 45,000 notes) in each song. This is way more internal song memory than most digital pianos in this price range which may have the capacity of 1, 2 or 3, or 10 songs at most. The G1 Air does not have audio wav or MP3 recording as a few other pianos have not does the piano have a USB flash drive input to load or save songs.
But I have found that most people just want a capable 2-track MIDI recorder-player on the piano to learn songs and have fun. Plus, if you record 2 separate parts with 2 different instruments and play them back together you can even play “live” on top of that with any other instrument you choose. So basically you can play along with your own recorded song and set the playback speed at any tempo you like…pretty cool.
Beyond that, when playing back a practice song you recorded, you can set up a specific passage or part in the music where you may be having a few playing problems and just have that part play over and over at a slow speed or while you play along with it (either right hand, left hand, or both) so that you can focus on just that set of measures rather than the entire song.
The G1 Air is capable of doing that too and it does help in a number of ways and you will become better more quickly. As a long time teacher I know this works because I’ve used this technology many times with students.
PIANO PARTNER MODE
Speaking of lesson practice, the G1 Air also has a Piano Partner mode which allows 2 people (siblings, friends, parent-child, teacher student) to practice the same song at the same time using the same notes coming out in the same octaves. This happens by the piano electronically dividing the 88 keys into two 44-note keyboards so that one person plays 2-hands on one side of the middle C and the other person plays 2 hands on the other side of middle C. The piano automatically adjusts the left part of the keyboard (the bass section) to sound identical to the right side of the keyboard (the treble section). Other digital pianos have this mode too and it can be called duet mode, 4-hand mode, twin mode, etc.
It’s a cool practice feature but only useful under the conditions I mentioned…same song, same notes with same sound, at the same time for 2 people using one or both hands depending on whether you’re practicing treble, bass, or both clefs.
CONNECTIVITY & INTERNAL SPEAKER SYSTEM
The connectivity available for this piano is pretty much what most people are looking for which includes separate line audio output jacks, MIDI in & out connectors, USB to device connector, and 2 stereo headphone jacks. The only thing missing that I would have preferred to see is an audio stereo line input jack to connect outside audio to go through the G1 Air speaker system. This would be useful to hear your music coming from your external personal device and being fed directly through the piano speaker system is that device did not have Bluetooth connectivity.. I say that especially because the G1 Air speaker system is by far the most powerful speaker system of any major brand or model under $2000 that I know of.
The G1 Air has 4 speakers, 4 amplifiers putting out 80 watts of total power being dispersed and diffused through a very impressive system of a fully enclosed boxed speaker system with 2 woofer speakers facing the player (just below the keyboard) and then 2 high frequency top speakers dispersing the sound upward into the air and deflecting towards the player just below the music rack pointing upward.
When I played this piano for the first time I was impressed with how full and yet clear the piano sound was coming out of this internal speaker system. For a minute I thought I was playing a real piano piano. I experienced very little if any distortion on full power and the dynamic tonal range and expression of the stereo concert grand piano sound was very good. It’s one thing to have an impressive key action and piano sound chip in or around the $1500 range but it’s another thing entirely to have a powerful internal speaker system to play it through.
In the G1 Air you can even feel the bass notes bring out the bottom end of the piano sound. Also, being able to clearly hear the higher frequency range without the overall sound being mid-rangy or muddy is no easy task in a small compact digital piano but in my opinion Korg has really nailed it. In other words, whether you play
this piano at low volume levels, medium volume, or you turn up the master volume all the way, in my opinion the G1 Air sounds natural like a real piano and even at low volumes it doesn’t sound “tinny.”
It doesn’t loose that low end bass sound that real pianos have whereas on most digital pianos in this price range when you turn down the volume then the bass frequency tones just pretty much disappear and the piano tends to sound like a toy. That’s why a lot of people who demonstrate digital pianos do so at loud volumes because anything loud will generally sound big. But it’s at the lower volumes where quality piano sound reproduction gets much more difficult to achieve through a typical digital piano internal speaker system. I also do not recommend anyone needing an additional speaker or sub woofer system for this piano…it’s got plenty of power and bass response for most rooms all by itself.
Anyone who says otherwise is trying to sell you extra stuff. Oh, and when you play it through stereo headphones for private practice, the internal stereo headphone amp is so good and powerful, it will also sound like you’re playing a ginormous grand piano through your headphones, assuming you have a decent pair of stereo headphones. In terms of the headphone listening experience, I have heard a few digital pianos in the $4000-$5000 range that cannot keep up with this Korg G1 Air in that way.
You can be quite a distance from the G1 Air in another part of your home from where the piano is and control the song volume and the songs that you are hearing right from your device without cables or any other wired connection. So even through the piano does not offer an audio input jack, it really has something better…a full Bluetooth audio connection and it’s so easy to use. As soon as you power up the piano the Bluetooth function automatically switches on and the G1 Air shows up on your device. Just touch the G1 Air name in your device Bluetooth list in settings and the piano and your device instantly connect (pair). That’s all there is to it.
Then you play your favorite song on your small device and hear it through the awesome G1 Air powerful internal speaker system your song will sound just as good through the piano speaker system as your live piano playing does.It’s a win-win situation. On top of that feature, you can also play the piano live with your songs coming through the speaker system and learn to play your favorite songs on the piano while listening to your songs. If you want to that in privacy then just plug in your stereo headphones and hear your iTune, Google Play, etc songs and your piano playing all together through your headphones without disturbing any one else. There is no other name brand digital piano under $2000 that has this built-in capability.
I have personally tried this feature many times on the G1 Air and it’s really awesome, especially because if you want to be in another part of the room or house you can still control your songs (within reason as far as distance goes) and the lack of an audio input is also not an issue. Now don’t get this confused with Bluetooth MIDI. Bluetooth MIDI is completely different and you will find that feature in this price range on Kawai and Roland digital pianos.
However, Bluetooth MIDI is simply a wireless connection to your iPad/iPhone device and you don’t really need it because you would need to be sitting at the piano to use those apps anyway so that the educational or instrument app can respond to the keyboard when you’re playing it. You can otherwise easily get that MIDI connectivity feature connecting a USB cable to the G1 Air instead of Bluetooth and then you can use all the MIDI apps on your tablet in the same way as you would with wireless MIDI.
But MIDI is not audio and not playing music through your piano wirelessly from another place in the room, which is what most people are looking for. Bluetooth audio is the cool feature and the Korg G1 Air has it.
On the G1 Air, the higher raised surface above the control panel will support the sheet music so that you can put three times as much music on the G1 Air as you can on the typical digital piano in this price range and the piano will support it. It has a long groove at the front of the music cover support for the music to sit in. Not only that but the music itself is at the correct height to look straight ahead for the proper eye position unlike some other compact digital pianos that don’t have this extra height.
The key cover on this piano is very special in my opinion because it’s a “slower-close” key cover so when you drop the cover from its tallest open position, the cover has a slow-down breaking system in it so the cover more slowly falls to the bottom and closes up…it doesn’t just slam down. So it you are a child in your home lets go of the cover while closing it, they won’t get their fingers cut off and the cover won’t slam down. Also, the key cover has a slow-open process with a break system in it. This means that when the cover is opened and you let it fall backwards to stop, the cover won’t just fall backwards and bang off the cabinet. It actually slows way down and softly settles backwards where it stops at its designated point. I don’t know of any digital piano in this price range with such a nice cover that also works so well and is practical in these ways.
When a company pays attention to cabinet details and offers more for the money, I am always impressed. The G1 Air also comes in three really nice looking colors including matte black, matte white, and a very attractive custom wood grain dark brown matte finish which no other piano manufacturer offers. The measurements of the piano is approximately 53″x 15″x 32″ without key cover opened and with key cover fully opened the height measurement is 39″ and the weight of the piano is only 90 lbs so it’s relatively easy to move.
The G1 Air has low power consumption, has automatic power shut off in case you forget to turn it off when you’re through playing it, and Korg products are known to last not just years, but decades. The factory warranty is currently 5 years parts and 5 years labor after you register the piano on-line with Korg.That warranty time is huge and larger than most of the other digital piano companies out there incl Yamaha, Roland, Kawai, etc for instruments under $2000
SHEET MUSIC SUPPORT
1. The height position of the music rest above the keyboard is more in the line-of-sight of someone reading sheet music than many other contemporary compact digital pianos can do because those other digital pianos typically have the music rest on the same level as the keyboard just behind the keyboard. Having the music sitting up at a higher position (like a real piano) can reduce neck strain, eye strain, and it allows the player/student to experience reading the sheet music in a more normal way.
2. There is a smaller groove built into the front top of the piano (see above pictures in previous cabinet info/comments) that spans the entire width of the piano which not only allows extra piano sound to project up & out of the piano (like what a grand piano does when the lid is open), but this groove can be use to physically hold sheet music and books for the entire width of the piano top and that music then has back support from the key-cover which acts as a natural backing for the music to stand up and be supported.
Utilizing the entire width of the piano top allows the use of more sheet music and books at the same time that most other digital pianos cannot do because those pianos just have a smaller designated music rack instead of being able to spread your music out across the
entire piano. This is very cool, especially for someone playing a more complex piece of music with multiple pages of music or for someone who wants more than one music book on their music stand at the same time. The Korg G1 Air does this in a way that few other digital pianos can.
3. The depth of the music support (from the open key cover) from is where it should be…closer to the player so that you can see the music better. There are many digital pianos where the music rack is set much further back from the person playing the piano so that you would have to look at the music much further away than would be normal on a real piano. So in this way the G1 Air is designed to make reading music more comfortable and normal.
4. The design of the key-cover when it is up and being used as the backing rack for the sheet music also allows for a music light to be clamped to the cover over the top of it. In other words, unlike many other (but not all) digital pianos without a secure, sturdy music rack (key-cover back) built like the G1 Air, this model let’s you clamp on one of those handy and durable small and compact LED “goose-neck” adjustable music lights that you can buy separately from places like Amazon so that you can read your music in darker places in your room, or at night when you don’t want other lights in the room to be on. The LED music lights with the secure clamps on them are the perfect solution for a music light on the Korg G1 Air and those lights are relatively inexpensive and can work on batteries or by being plugged in. Most of those lamps also have 2 light levels including bright and less-bright.
KORG DIGITAL PIANO FACTORY
One more thing that I nearly forgot. Most of the Japanese brands including Yamaha, Casio, Kawai, and Roland design their digital piano products in Japan but have them built and assembled in other countries such as China, Indonesia, and Malaysia, as I mentioned earlier. That’s fine as long as the manufacturer owns and runs the factory in that other country. Quality control in products is extremely important and all the strong, respected digital piano companies want their products to turn out good. However, having them build their products in Japan itself can be quite costly because
costs of living and wages are so high as compared to many other countries such as China so that’s why the actual manufacturing for these digital piano companies don’t happen in Japan anymore, they just cannot afford it.
But the upside in making things in Japan is that it is known over the years that the quality and longevity of the products built in Japan by Japanese people has been normally higher than in other countries such as the ones I mentioned. But having them made in the US isn’t going to happen because of distance, costs, and business restrictions But having them made in Japan is the next best thing. The Korg company makes their G1 Air in a Korg owned and operated plant in Japan.
FINAL THOUGHTS & MORE CABINET DETAILS
I believe that at the end of the day, if you cannot find something to like about this new digital piano model then you are not trying very hard! If you want a piano primarily to play piano on with fewer bells & whistles than other digital pianos (but still with some cool ones like I described earlier), and you’re also wanting impressive grand piano playing sound quality and a satisfying piano playing experience for under $2000, then in my opinion you cannot miss with the new Korg G1 Air.
Very good review,Tim. Since this board only allows Bluetooth audio for songs,can you connect your I pad via USB to host and utilize your I pad apps with this digital piano?. Thanks for having this review of the g1 air.It looks like a bargain for what it does.
Px870 vs korg air, which one do you recommend?
Wow, you basically convinced me to buy this piano!
What can you tell about piano action being kinda old for 2018, key wobbles and clicks? I was considering Kawai ES8, but its much more expensive with the stand.
Howard, I have updated my G1 review to make my USB comments more clear with regard to your question. Yes, you certainly can use MIDI interactive apps for tablet by connecting a USB cable (and adapter) to an iPad from the tablet. If you live in the US and want a G1 or other digital piano then please email me and I can help arrange for you to purchase for even less money than internet and amazon discount pricing.
The Kawai ES8 is at a different level of piano sound sampling key action, and pedaling. But it should be given it's much higher price range. As for being "old" the ES8 key action, piano sound chip, and pedaling are being used in 2 model Kawai digital pianos with a total of 5 Kawai models using that same key action and many people who own those pianos have great things to say about their playing experiences. Just depends on your budget and preferences
they are both great choices. Just depends on your budget (price range) and also the features and functions that most appeal to you.
If you live in the US and have further questions then please let me know and I can also show you how to purchase either piano brand new for less money than internet and amazon discount pricing.
Hi Tim,
Great review of the Korg G1.
How would you compare the G1 to the Kawai KDP90? The KDP110 is obviously around $300 cheaper($200+$100 for the included bench).
Also what's your opinion on the C1 Air?
Thanks,
John
Thanks Tim .You answered my question.Pleaseskip over this subject in my recent e mail to you. I think this Korg digital piano is probably the best console digital piano in its price range along with the Casio's Px consoles. Keep up the good week- You' re making a difference!
Hi Tim, thanks to your comprehensive and detailed review, I have gotten myself a Korg G1 🙂
In your review, you mentioned that the piano does not have audio WAV and MP3 recordings. So, how can one still make a recording of the songs to be played back on the computer?
you could purchase an external audio wav/MP3 stereo recorder and connect it to the audio output of the piano. You would then record your audio performance on that device and save it to a USB flash drive or memory card and then transfer that recorded song into your computer for storage and use in software programs. The external audio recorders are generally quite inexpensive…near or under $200US. Then you would get what you are asking about.
A clarification on the USB port on the G1 Air is that besides its possible use as a MIDI connection, it also has an alternative USB storage mode. While the G1 Air cannot export audio wav/MP3 files, if you need more than the 99 recording slots built in (or if you just want to back up to or restore from a computer your compositions), you can do so using the USB port.
For both the C1 Air and G1 Air, although you don't have built-in bluetooth MIDI to connect to iPad app like some other piano brands, you can use a Yamaha or Quicco bluetooth MIDI adapter instead of a cable, particularly since they only cost about $5-$10 more than a physical cable. For the G1 Air you can also use a Bluetooth USB adapter, though it requires power and costs about the same as the MIDI version, so it isn’t the preferred solution.
A good choice for a Bluetooth MIDI adapter that works well with the G1 Air is the Yamaha MD-BT01, so you can keep your USB port open to use as a means to back up songs from the piano to a computer and still have a wireless connection to an iPad.
Dear Tim,
What do you think about Roland 140.
Compared to korg G1?
Hi Tim,
My new piano arrived yesterday afternoon, assembled easily, and plays beautifully!
Thanks so much for another smooth exchange. You deliver such great value through your in-depth reviews, and of course, your factory direct prices are icing on the cake.
Having bought two pianos through you this past year (this one, and the Kawai ES8 for my girlfriend), I don't anticipate being in the market again anytime soon, but when I hear of others who are, I'll be sure they at least visit your site before they make any buying decisions.
Thanks again,
Chad
Update: one week in and I'm in Love! Great action, amazing sound – through the speakers and through headphones, and a total bonus that it's now my stereo system for playing mp3's from my phone or computer. Awesome!
Chad, happy to hear you love your new piano and that it is living up to your expectations! This is why I do what I do…to help people become musically happy with the right digital piano that will fit their musical needs and budget, and also be a long term enjoyable experience.
Hi Tim,
I'd like to ask, how would you compare Korg G1 to Roland DP603? The depth of the cabinet is crucial for me that's why I have narrowed down the search to these two instruments. I will be playing mostly on headphones. In my region the Korg is approximately 400 Euro cheaper.
As I understand both have excellent and quiet action and Korg might have more natural piano sound.
Is there something that would make you choose Roland over Korg?
Thank you!
My god where can i start, i've been playing piano for about 1 year and a half but i never owned a piano so i only played whenever i could find a public one somewhere, a couple of months ago i decided to start looking for a digital piano and you are the only reviewer online that i really trust, i've been reading a lot of your reviews and every single one is just amazing, the amount of quality in the information you give is remarquable, your critics always feel geniune/unbiased wich is hard to find online, i have a budget of around 1500$ and thanks to your reviews i think i have my mind set on the Korg G1 Air, i only care about the key action and the regular grand piano sound, all the other features that digital pianos have are irrelevant for what i'm looking for, i do have one question about the key action on the G1 air, i've only tried a couple digital pianos (up to 3000$) in a music store and the thing that bugged me the most is that towards the top part of each key it gets a lot harder to press (compared to a yamaha baby grand that i'm used to playing) i would assume that it's because digital piano cabinets are not very deep so there isn't enough space to get a more balanced pressing feel up and down each individual key but that's just a guess, do you understand the issue i'm describing? does it apply to the G1 air?
and again great reviews man the time you put in each one really shows.
yes, a grand piano key action with much longer keys is easier to play because of the extended key length and balance points from front to back of each key. This is normal. On acoustic upright pianos the backs of the keys are noticeably firmer to the touch than the fronts of the keys simply due to mechanics in the upright key action design. And yet most people in the US who own and play acoustic pianos have upright pianos with the upright key actions, and their teachers don't complain because this is just they way those pianos are and much music can be made on them. The G1 Air like just about all other digital piano key actions have keys more like upright acoustic pianos in terms of key weight…but that's fine and is normal. Only for people who regularly play acoustic grand pianos will they notice a difference. To get a "grand piano type key action" in a digital piano would require spending at least twice as much money as compared to the G1 Air.
Hi, amazing site and really really useful reviews, all to the point. I am about to choose between Korg G1 and Casio PX870. i know there is a difference in price range but is there an obvious reason to choose casio over korg? Unfortunately where I live it is hard to try them.
And a crucial question that noone has managed to answer me so far. About G1. If I connect G1 with an IPad via cable, and use it as a midi keyboard for an app, lets say Garageband, can I also connect back IPad with G1 via Bluetooth, so that I can listen to Ipads sound through G1 speakers? If yes, should I expect serious lag?
Thanks, and keep doing what you do <3

I had purchased this piano as a gift for my wife today. Hope she likes it.
What would be the equivalent Korg model in a non cabinet digital piano?
The closest Korg portable digital piano to the G1 Air would be the SV2S which sells for about $2500
Thanks for this great review, Tim. Here in the UK I am struggling to find a Korg G1 to try out in person.
One question, in your opinion are the anti-tipping brackets completely necessary? Does the piano tip forward without them? Just thinking of the restricted space in my room.
Many thanks! Simon
The anti-tip brackets that attach to the bottom legs on back of the piano stick out about 3" long. If you have a flat wall that the piano will be sitting against, then brackets will likely be unnecessary because the piano won't be able to tip backwards because of the wall.
The brackets are designed to prevent the piano from tilting backwards and tipping over if there is no hard surface directly behind it. If the piano is not against a wall then the brackets are necessary. I hope this helps. Overall, the G1 Air is a very impressive digital piano when it comes to the piano playing experience and build quality.
Thanks for this great review, seems like a great choice for me. I have one question related to recording myself onto Garageband. I assume this needs to be done by connecting the cable with the midi in/out? Also, would it need special cables to connect?
Thanks,
Arnold in Canada
Thanks Tim – appreciate the blog. I’m in a similar boat to some, having played acoustic pianos growing up and looking for my first digital with a young family.
I want a slim, modern cabinet with a budget of circa £1500 UK. I like the idea of textured keys and preferably wooden (but not essential).
It seems like the Yamaha S55 would fit the bill, but the Kawai CN201 has a better sound (but more traditional cabinet), whilst the Casio PX-S5000 or 6000 is very modern and has wooden keys but will have inferior sound due to the speakers and cabinet. Korg Air could be a good choice but lacks the app etc.
Any other thoughts to consider?
Thanks.
Based on your music needs and criteria, in my opinion the Korg G1 Air would be a great choice. It can connect to iPad, etc and provide great playing/learning experience with many 3rd party music/piano related apps. It does not have it's own proprietary controller app, but the G1 Air is relatively simple to use so it really does not need a controller app.
The internal piano sound engine and internal speaker system make this model sound like an acoustic baby grand piano when it is being played. The non piano instrument sounds are also very impressive and the Bluetooth audio streaming feature can be very useful.
I personally do not like the Yamaha S55 for one main reason; the key action is extremely heavy and can cause hand, finger, and wrist fatigue. Touch-weight measured at middle C for that Yamaha is approx 90 grams! Any piano that has touch weight on middle C over 75 grams is simply not acceptable for recreational playing or even for advanced pianists based on my experience playing all kinds of pianos for many years.
Other than this Korg G1 Air model and a couple of the ones you mentioned, my other suggestion for a great piano playing experience around $2000 or so would be the Kawai ES920.
In addition to all of that, maybe you could design and make your own digital piano to satisfy all your specific needs:)
Great review. I Am struggling to find somewhere local in the south west area of uk to try out the g1. I currently have had cvp6 for 30 years and want the best replacement money will buy. It will be in a small room and cannot be myuch taller or wider than the cvp6. I have short listed the cn301, es920 and the g1. My main need if best piano sound and action for classical music. I like the look /sound of the g1 in photos/ videos on line. I worry it is by far the cheapest. What are your thoughts please?
Colin P
Greetings Tim
I need your opinion on Choosing a Home full Cabinet Digital Piano that I won't need to upgrade for upto 20+ years that's suitable for beginners to Advanced Classical level pianists. That has the most Authentic Action (Keys and pedals) in all aspect with a Authentic Piano sound Sampled or modeled , Durable and Sturdy built in cabinet and internal Action in the $2K range max.. I think I'm down to these 3 options (Roland HP-704/Korg G1B Air/Casio AP-470) although not sure if any of these three fits the bill that's why I need your opinion. Also do you ship worldwide?
Thanks
Hi Tim – great review.
Assuming a both were within budget, would you choose a Yamaha CSP 170/275 or the G1 air and save ~$1,000?
How would you compare the key action of this piano to that of Roland HP704? Would you unequivocally say that the Roland would be a step up, given the price difference?
