REVIEW - Korg C1 Air Digital Piano - Impressive!

Korg C1 Air cabinet & control panel picture🎹 UPDATED REVIEW - July 13, 2018 - Korg C1 Air Digital Piano - Recommended - Korg is a well known music products manufacturer which is based in Japan. They have been designing and producing a variety of pro and home music products for over a half century and continue to be a leader and innovator in the digital music world. With regard to digital pianos, Korg recently came out with an impressive model called the C1 Air home digital piano ($1399US internet discount price*) which incorporates all new Korg piano technology at a relatively low competitive price. Although Korg has been making digital pianos and digital music products for decades and I personally have played many of them, they have not been as well known to the general public (families, non pro players) as they have been to professional musicians. In the home digital piano market Korg has had some low priced digital pianos (mostly portable) available for quite awhile but they have not been near as popular as compared to the more well known brands like Casio, Yamaha, Kawai, and Roland and in my opinion not very competitive with those other digital pianos under $1000. But now with the introduction of a few new models over $1000, Korg is finally showing they can make a very well built  competitive digital piano, especially in this price range between $1000-$1500. See bottom of this review for special lower discount price info. (click on pics for larger views)

Korg C1 Air cabinet & control panel pictureThe first thing that shoppers generally want to know concerning digital pianos is about the key action. How does it move, how does it feel, how will it hold up over time, is the key action quiet or noisy, will it emulate a real piano action, and most of all, is the key action good enough so I grow into it rather than grow out of it? Piano teachers, like myself, also feel the key action is the most important part of any piano whether that piano is acoustic or digital so it is the number one thing to be concerned about, especially if you are a piano student or someone who plays well. The Korg company basically builds two key actions for their home and professional digital pianos. They have their lower quality, less realistic key action, and they have their top of the line acoustic style key action called the RH3 which is what is used in the C1 Air. The best way for me to describe the RH3 key action is to say it's very impressive given the low price of the C1 Air model. In my opinion the feel of the RH3 key action movement is so good, so organic, and so responsive for a lower priced digital piano like the C1 Air you really get the impression you're playing a real acoustic piano. The RH3 action is balanced well up and down the keyboard as well as front to back of the keys as compared to many other digital pianos in this price range, properly graded in down weight movement and is not too heavy and not too light. The overall movement of the keys really allows a player to connect with their music and feel like they can really express themselves. There is no other key action under $2000 for a furniture cabinet piano in my opinion that feels quite like this Korg top-of-the-line key action in terms of the way it moves. Yes, there are other key action that are nice to play from Kawai, Roland,Casio, and Yamaha, but the Korg RH3 key action is really in a class by itself as far as I am concerned, plus, it's a noticeably quieter key action in terms of noise coming from the keys when they move up & down as compared to other digital pianos out there.

Korg C1 Air cabinet & control panel picture
Korg RH3 action picHowever, there are two things about this key action that Korg does not offer which other key actions in this price range do offer and that is "ivory & ebony feel keytops" and "escapement function." Some of the digital piano manufacturers are producing a special material that goes on the tops of the keys which tries to simulate the old ivory and ebony that regular acoustic pianos used to have many decades ago. Ivory and ebony haven't been used on regular piano keys in a very long time so what real piano keys have had for many years is the hard white implex acrylic key tops and black matte keytops. Ivory and ebony had a different appearance than they way acoustic piano keys are now and one of the properties of Ivory and ebony is that they were a porous organic material so they helped to absorb sweat from the fingers although the sweat discolored those materials after awhile. With regard to the "escapement" key function, this feature is found mostly on grand pianos when you press a key very slowly you would feel a hesitation or notch about half-way down key as the key is depressed very slowly. If the key is depressed faster then there is no escapement feeling so the keys move freely. What some of the manufacturers have tried to do is to recreate that escapement feeling in a digital piano key action. In this price range when it comes to both ivory/ebony imitation keytops and the escapement feature, so far only Roland has both features whereas Casio is the only brand with just the ivory/ebony feel keytops in this price range on a home digital piano. Yamaha does not have either feature in this price range not does Kawai or Korg. The reason why most manufacturers don't try to recreate these things in this price range in my opinion, is that at the end of the day it does not really matter because these features are just an imitation of the real thing and for most people matter very little when it comes to the actual piano playing experience. A real upright acoustic piano does not have either feature as they have white acrylic keys and no escapement key feeling, and yet most people who have acoustic pianos in their homes, schools, and other venues mostly play upright pianos. In other words on the Korg C1 Air, the key action emulates a fine upright piano key action along with moving quickly like a grand piano. So the bottom line is...I would not get "hung up" on features that may not improve the piano playing experience for you. I personally would much rather have a key action that moves very smoothly like the Korg RH3 rather than a heavy, fragile, or unresponsive key action that has the artificial keytops and escapement. That's how much I enjoy playing the Korg C1 key action over many other digital pianos, even some of the key actions in the $2500 price range!

piano sound dynamics
Piano sound is a tricky thing because for many people who don't have piano playing or piano listening experience, they may not know what a piano is actually supposed to sound like? In other words a piano shopper could mistake poor piano sound reproduction in a digital piano with something they think sounds OK or good. I see this happen all the time because a lot of people don't know what it actually takes for a real piano to sound good and natural. There are so many organic resonances and vibrations going on in a real piano when it's being played, and to reproduce all those natural organic piano tones, string vibrations, and cabinet vibrations is not easy in a digital piano. Some poor sounding digital pianos like some models made by Artesia, Suzuki, Kurzweil, and others have very poor (almost embarrassing) piano sound reproduction and in fact a few of those pianos sound like toys in my opinion. Even some current model Yamaha digital pianos in the Arius series ($1100 - $1700) have piano sounds that are quite compressed and they don't seem to offer a good expressive dynamic piano tone as compared to other digital pianos in this price range such as this Korg C1 Air. Good, expressive, dynamically exciting piano tone is important especially for students who want to grow in their musical abilities and for people who already play well and want a better, more natural piano sound experience. So when I played the Korg C1 Air, I was not only impressed with the stereo piano sound itself, but was also impressed with how big and full it was. This piano may be compact in looks but it is definitely not compact in piano sound.

Korg C1 Air cabinet & control panel picture
Korg C1 Air cabinet & control panel pictureTo help that piano sound chip along, the C1 Air has the most powerful internal speaker system in this price range (less than $1500) that I have ever heard. At 50 watts of power with 2 specialty speakers housed in its own speaker box pointing towards the player and the room, the fullness and big bass reproduction of the speaker system produces an impressive stereo piano sound that really does sound as big and full as an acoustic grand piano. I don't know how Korg does it in such a compact cabinet footprint but if you had your eyes closed and heard this C1 Air piano sound you would  think the piano was three to four times a big as it really is...quite amazing actually. Also, because the internal speakers are not under the cabinet pointed down to the floor like so many other digital pianos in this price range are including from Roland, Yamaha, Kawai, and others, the powerful front facing speaker system in this piano really does fill up a big room without a problem with a sound like a big grand piano. If fact, the sound is also clearly heard above the keyboard towards the player's ears so you get a sound emanating from many places in the cabinet so that it sounds more natural. With sympathetic vibrations, pedaling resonances, huge decay-sustain time just like a big grand piano, the C1 Air internal speaker system combined with its impressive stereo piano sounds including a European Steinway grand piano sample and a Japanese Yamaha grand piano sample really put out a sound that in my opinion will make you say "WOW" I can't believe it! That's how good this piano sounds in this price range (under $1300) for a self contained compact digital piano, there are no other brands or models that come close in my opinion, especially in this type of cabinet. Now for some people who play real pianos they can normally tell the difference between a digital piano and real piano sound because in a digital piano the sound comes out of speakers rather than through a wooden soundboard in an acoustic piano. But for most people the piano sound of the C1 Air will be more than sufficient and natural and you can enjoy it very much. You can also spend less money and get a good piano playing experience in other digital pianos and you can certainly spend a lot more money and get an even more authentic piano playing experience in another digital piano like the higher priced Korg G1 Air. But if you want to keep the price between $1000 - $1500 then the Korg C1 Air should be a definite consideration.

Korg C1 pic Korg C1 pic Korg C1 Air cabinet & control panel pictureOK...so how about polyphony...some people wonder if that specification really matters and if they should be concerned about it? The answer is...polyphony only really matters if when you play the piano the notes all play and sound normal and sustain properly without notes abruptly dropping out. If the piano you are playing can play normally without any issues then the amount of polyphony it has in it will be enough. If the piano sound has sudden interruptions of notes when playing the piano normally then there is not enough polyphony, otherwise known as piano processing power. If you layer or mix two instrument sounds together then the polyphony needs to be powerful enough to handle the extra sound so there are no sudden note dropouts. If you are playing a digital piano where there is a multitrack (8-16 track) MIDI recorder-playback feature (which the C1 Air does not have) then added polyphony becomes more important to handle all the notes that are recorded or simultaneously playing on all those tracks and I would recommend getting a digital piano with the most polyphony possible in that case. This is when more polyphony becomes more important. In the case of the Korg C1 Air, it has 120 notes of polyphony processing power which is fine for what the C1 Air does...and that is mainly for piano playing, layering 2 sounds together, or recording and playing back a two sounds (left and right hand) maximum. I had no issues with 120 note polyphony when I was playing the C1 Air stereo piano acoustic sounds and the only time I heard any note drop out was when I layered the most memory intensive sounds which are the stereo piano and the stereo strings and played large arpeggios with lots of pedaling sustain. But few people will actually play like that because it's not normal. I only do it to test out the ability of polyphony to be uninterrupted and in the "real world" and under normal circumstances, few people will ever play the Korg C1 Air in that way. Although there are other digital pianos that have higher polyphony such as 128-note polyphony, 192-note polyphony, and 256 note notes of polyphony in terms of their specifications, in reality the 120-note polyphony in the C1 Air is plenty for most people including myself and it will provide enough piano playing power to handle all your piano music.

Korg C1 Air cabinet & control panel picture
When it comes to pedaling, that is a part of piano playing which can be easily overlooked, especially if you are a novice or have never played a piano. In the beginning using pedals, especially the damper-sustain pedal, is not something that you do until you are well into your lessons and maybe not even until a year later will you need to put any emphasis on pedals and how they work and how you use them. However, if you keep practicing or you already play piano then having good working pedals that operate properly is an absolute necessity, particularly with the right pedal (not center or left) which is called the damper or sustain pedal. That pedal is what most people will use over 90% of the time as compared to the other pedals and if that pedal does not do its job, work and respond smoothly and quietly, and offer a good half-damper feature, then you will be sorely disappointed later on when you really need that pedal to enhance the music you are playing and make it sound good. Beyond that, the pedal sustain decay time and volume needs to be long and full for all notes and that is definitely something I find missing on many digital pianos because of using cheap pedal parts and limited memory for decay & sustain time and volume. In other words, if the pedals are not working like a real piano and the piano sustain tone is not sounding like a real piano then you will likely be very sorry later on when you discover it because there is nothing you can do to change it on the digital piano you have if its not good.

Korg C1 Air cabinet & control panel picture
Another thing about the pedals on the Korg C1 Air is that I was very impressed with their ability to play responsively, feel like they are built well and durable with quiet pedal movement, and I was especially impressed with the sustain pedal piano decay time and sustained volume loudness across all 88 keys when using the damper pedal. In other words you can hear the notes you are playing blend altogether in a natural way with no choppiness or quick decay time like you might hear on some other digital pianos. The notes resonated for a very long time while holding down the damper pedal with lots or organic sympathetic string vibrations being heard. Also, the C1 Air produces realistic damper resonance when applying the damper pedal to give the piano tone, particularly in the upper octaves, a natural texture and resonance to the piano sound that is definitely heard on all real acoustic pianos but is missing on some digital pianos. Without these natural tonal resonances provided by the C1 Air pedals and the piano sound chip, a digital piano sound can be very artificial and fake, but in my opinion the Korg C1 Air really shines through and sounds much more like a real live piano with more sonic textures. It makes your music become more expressive and allows you to get the kind of "feedback" from your music that is necessary if you want to grow as a player. The middle sostenuto and left soft pedals work properly and will allow you to use those pedals correctly when your music calls for them to be used.

There is a lot a person can do with the functions and features of the C1 Air and it offers a variety of different instrument tones from a total of 30 individual sounds within 10 group instrument buttons with 3 variations per button with 26 of those sounds being non-acoustic piano instruments which include some impressive string symphony sounds, organs, electric pianos, harpsichords, and other usable tones. As I mentioned before there are 2 main stereo piano sounds including a German Steinway concert grand piano and a Japanese Yamaha concert grand. Korg also provides a few acoustic piano variations of those Korg C1 Air cabinet & control panel picture 2 concert grand pianos and I found overall that the variations are quite different as compared to their original tone because the original Steinway and Yamaha piano samples on the C1 Air have an abundance of pedal resonance being triggered when using the damper-sustain pedal. The damper resonance on the C1 Air is like hearing a lot of natural echo in a regular acoustic grand piano when the felt dampers are off the strings while holding down the damper-sustain pedal as you are playing notes. It's very impressive and adds a of character to the over piano sounds. Two of the piano variations of both piano tones do not have the damper resonance effect so the sound is a lot more plain without any echo at all while the other variation on the Steinway grand piano tone also has damper resonance but starts off a bit brighter in done as you play more delicately.  When using the piano sounds with damper resonance I also noticed that the fullness and sustained piano decay time was noticeably longer and richer in the upper octaves which is just like it would sound on a real acoustic piano. So Korg did its "homework" when it comes to reproducing exactly the characteristics of an acoustic piano...even in the upper octaves. Some people may like a pplainer tone without the resonance effect but other will enjoy the full resonating piano tones when the damper resonance effect is automatically applied when using the C1 Air damper pedal. I personally prefer the natural damper resonance which adds a lot of tonal flavor and color to the music. I definitely believe these C1 Air piano sounds overall are more natural and expressive than the Yamaha and Roland digital pianos in this price range especially given the deep, full piano sound being generated by the C1 Air speaker system.

Korg C1 Air cabinet & control panel picture
Korg C1 Air cabinet & control panel pictureAs far as other things you can do with the instrument sound selections is being able to mix (layer) any 2 of the instrument sounds together by pressing any 2 instrument buttons at one time to mix those sounds to play a song. So whether it's a guitar with choir or piano with strings, or even 2 different acoustic pianos mixed together at the same time, the C1 Air can do it well. By the way, some of those extra instrument tones are absolutely outstanding and the strings are especially good (realistic & full) when combining with any primary tone like acoustic piano, electric piano, guitar, harpsichord, etc, much more so than a few of the other brands in this price range...and I have played them all. You can even use the three preset piano & bass split sounds (located in 10th instrument group button) to instantly & automatically have a convincing bass sound on the left hand and a piano sound on the right hand to play a bit of jazz or rock which is fun to do and sounds great assuming you can play like that! There are 3 preset combinations which are all different and the left hand bass tones even respond to velocity and change dynamics as well as you press the key harder. Having 10 individual instrument group buttons on the C1 Air in my opinion is a much better system to quickly access your instrument sounds rather than having to cycle through all of them one at a time like you need to do on other brands with only one function button or rely on an external iPad app by that manufacturer to see those sounds. Although I like having a proprietary controller app which some other manufacturers provide for their digital pianos, you always need to have your iPad connected and opened up to use the app and it can also get in the way of you easily accessing and using all those cool educational or "music playing" apps that you may want to interact with instead of the controller app.

Korg C1 Air cabinet & control panel picture
Korg C1 Air cabinet & control panel picture The C1 Air control panel is located on the top left hand side of the piano above the keyboard. It consists of a large, easy to use master volume knob and 6 direct access buttons  near the master volume know. Those 6 buttons consist of accessing the song playback system, transpose key, touch sensitivity control, brilliance adjustments, reverb echo effects, and chorus effects. Many digital pianos in this price range don't have all of these important direct access buttons to quickly use popular features so Korg C1 Air cabinet & control panel picture it's a lot less intuitive to find those features in other digital pianos using their digital piano operating system. It great to be able to change the tonal character of the C1 Air by increasing or decreasing the brightness or mellowness of the overall sound. The same is true for the reverb and chorus effects which also changes the character of the overall sound in a good way and the adjustable reverb echo system is very impressive in creating an ambiance in the piano to where it can sound like the piano is being played in a big concert hall or auditorium. Being able to quickly change the transpose key or the touch response is also useful especially when you want to do it fast in a performance situation. Next to those 6 function buttons are the 10 instrument group buttons (as mentioned above) with 3 variations (called banks) in each group for a total of 30 internal instrument tones as I mentioned before. There is a function button within that group of 6 direct access buttons and the function button allows you to edit a number of things within the piano. You just touch the function button and then the 10 instrument sound group buttons become the different function access buttons for those editing features. Included in those editing functions are master pitch change, 3 new temperament scales, relative volume balance when layering/mixing 2 instrument sounds together, octave change mode, and a few other useful functions. There is an LED display on the right side of the instrument group buttons that reads out the various names of instruments and functions when they are selected. I would have preferred an LCD display which would have been more effective and intuitive to use but Korg chose the older style red letter LED display. It actually works fine because there aren't that many functions on the C1 Air to figure out which is helpful.

Korg C1 Air cabinet & control panel picture
The C1 Air also has a mode called "Piano Partner" which allows two people to play or practice the same song playing the same notes in the same octave. This is good if there is a piano-student, parent-child, of 2 siblings who are wanting to play the same song. The piano electronically divides the 88 notes into two 44-note keyboards for each person to play. So two people play the same notes with one person being on the left side 44-keys of the piano and the other person being on the right side 44-keys and both can hear each other with the far left pedal being the sustain pedal for the left side player and the far right pedal being the sustain pedal for the player on the right 44-keys. It actually all works pretty easily but it's only useful if you have 2 people wanting to practice the exact same notes at the same time with the left side keys being able to automatically convert to the same octave pitch/sound as the right side 44-keys. It's actually easier than it sounds but unless you have need of this feature then you'll likely never use it.

Korg C1 Air cabinet & control panel picture
Korg C1 Air cabinet & control panel pictureThe 2-track (2-part) recorder/player on the C1 Air allows you to record a left and right hand part separately so you can play one at a time and then play them both back simultaneously or record one part/hand and then play the other part/hand live with the recorded part. This is really useful and practical when learning how to play a song using both your left and hand hand playing separate parts with bass clef and treble clef. It helps you hear how you are actually doing and it's also like having a teacher with you because once you learn and play one part and record it, then you'll be able to play that part back as often as you want to and then play the other hand/part against it so you have something to play with. It's like someone playing one hand while you play the other only it was you who played the first part...you just recorded it for playback so it could be heard while learning and playing the other hand. This is a very cool feature for any piano student, especially as you become a little more accomplished in your playing. The C1 Air also has an adjustable tempo digital metronome to help with your timing and rhythm which is very important, so that is good. Unfortunately the C1 Air can only save a maximum of 1 user recorded song so if you want to record another song you need to record over the previous song which is a limitation as I would have preferred there to be more user song space to save multiple recordings. For some people that won't matter but for others it will. Inside the piano memory are 40 well known classical piano pieces that you can play back and listen to or play along with. You can control the volume of those songs, the tempo faster or slower at whatever speed you desire, and you can even mute either the left hand or right hand parts if you want to play along and learn the parts separately from sheet music you can buy. The classical songs in the 40-song library are the original full arrangements and will play one after the other automatically so you can just use it like a player piano if you want to and listen to them as they are (in my opinion) beautiful to hear and relax by. Korg does have their upgraded model called the G1 Air which can save and play 99 recorded songs, so that model has virtually no recording limitations in this way. The G1 Air also has other recording functions as well as other interesting features for people who want to upgrade assuming you have a slightly larger budget to do so.

Korg C1 Air cabinet & control panel picture
Korg C1 Air cabinet & control panel pictureWhen it comes to connectivity to the piano, the C1 Air has a stereo line output and 2 stereo headphone jacks along with MIDI in/out connectors. Unfortunately there is no USB to external device connector so the only way to connect with a tablet (iPad) or computer to use external software or apps is to purchase an adapter cable with MIDI connectors on one end and a USB connector on the other. This would allow you to connect the C1 Air to an external USB device with that adapter but it would have been a lot more convenient and intuitive if the C1 had a regular USB connector built in like just about all of its competition does. That's something which Korg should have done but for whatever reason did not do which is a disappointment to me. But at the end of the day an adapter cable will make things work but they will cost you approximately $40US. I will mention that when plugging in a pair of stereo headphones, the C1 Air has a special circuit built in called "sound optimization" which gives the headphone sound more of a 3D type surround sound effect kind of like you aren't really wearing headphones because the sound feels like it's going around your head and ears rather than straight into the ears as it would otherwise without that feature. Actually I do like it, but not all the time as the regular stereo headphone sound can actually be more natural sometimes depending on the music you are playing and the sounds you are selecting. Fortunately you can turn that "surround sound" feature on and off depending on what you want. Speaking of wearing headphones, the stereo headphone amplification circuit inside the C1 Air is so good and so powerful that it literally sounds like you are hearing a grand piano in your head when wearing a good pair of stereo headphones. The sound is loud and clear and very powerful assuming you like it that way, but of course you can always turn the volume down to whatever level you like. Some other digital pianos in a variety of price ranges that I have tried when using headphones can sound under powered and small, but not the C1 Air. Playing in privacy using good headphones is really an amazing listening experience as far as I am concerned and those kinds of things do impress me.

Korg C1 Air cabinet & control panel picture
As far as the internal audio sound system goes, as I mentioned earlier in this review, that's where the C1 Air is really impressive and makes the piano sound like it's gigantic in size. The way the sound projects out of the speaker system and the fullness and richness of the tone is really surprising given the smaller compact size of the cabinet. When it come to big piano sound that will give you the impression you're actually playing a real grand piano, the C1 Air really blows everything else away in this price range with its 50 watt powered sound system housed in its own speaker box chamber which helps the sound resonate more naturally. The sound also comes right at you instead of projecting away from you as it does in other digital pianos. It's immediate soundKorg C1 Air cabinet & control panel picture gratification and in my opinion that's what a lot of piano shoppers want...to be able to play a digital piano and have that piano really fill up the room like a real acoustic piano instead of sounding small and somewhat anemic like some other digital pianos can do. For instance, the Roland F140R compact digital piano which sells for $1199US only has just 24 watts of total power with 2 separate speakers. The Yamaha Arius YDP143 ($1099US internet price) has just 12 watts of total power with speakers pointing down underneath the piano rather than towards the player. The sound of that piano is definitely tinnier and thinner and it's due to the under-powered speaker system with speakers pointing down towards the floor. It's one thing to offer a reasonable good piano sound chip in a digital piano but if the internal speaker system can't put it out in a way that it sounds really good then that's a problem as far as I am concerned...unless the piano is in a smaller room or you generally want to play the piano quietly most of the time, then it's fine. But for me, I like like the piano sound to be able to be full and bassy, and resonate when I want it that way, and the C1 Air will really make that happen for you. I did notice that the piano sound could have been a bit more clear coming through the C1 Air speakers with more treble high frequency definition. However, if you increase the "brilliance" control on the piano with a higher amount of brightness then that livens up those higher frequencies a bit more which makes the sound clearer and more defined. The upgraded and slightly higher priced Korg G1 Air has an even more impressive internal speaker system than the C1 Air so if you want to check that one out you can do it here at the following link: Korg G1 Air Review 

Korg C1 Air cabinet & control panel picture
Now we need to ask the question...why does Korg call this piano C1 "AIR?" Well it's not because there is air in the piano or that the piano flys in the air. It's because the C1 Air has wireless Bluetooth connectivity to allow an audio song from an external device to be sent "through the air" to the piano speaker system so that you can play hear a song from your Bluetooth capable cell phone or tablet (iPad), or computer music library through the C1 piano without need of connecting cables. This is a very cool feature and no other top name brand digital piano under $1500 that I know of can do this. You can then take your music on your device and use the powerful internal speaker system in the C1, as I described earlier) to listen to your songs from another part of the room or another room nearby so you can play your music and hear it in a way you may not have been able to do before in your home, studio, Korg C1 Air cabinet & control panel picture school, church, or other venue. This type of wireless connectivity also allows you to play the piano live along with your pre-recorded music to learn the song or just have fun playing along with your favorite songs. Bluetooth audio is all about hearing your MP3 or audio wav file songs and not about Bluetooth MIDI connection or any other MIDI connection. I have personally tried this Bluetooth wireless audio through the C1 Air and it works great and automatically pairs (connects) your device with the C1 piano without needing to do anything special...it just works smoothly and easily and sound great. If you have never tried this type of thing before you'll likely be surprised just how awesome this technology really is and how much fun you can have with it.

Korg C1 Air cabinet & control panel picture
The piano cabinet is a nice small size which can fit into many small spaces and it come in 3 attractive cabinet colors including matte black, matte brown, and matte white. With the piano key cover closed the C1 Air measures just 53" wide x 14" deep x 30" tall. With the key cover opened up then the piano height becomes 36" tall. The weight of the piano is just 77 lbs so it's very easy for 2 people to move it around. Another nice cabinet feature is that unlike other digital pianos in this price range including digital pianos for slightly more or less money, the C1 Air has front connected support legs built into the piano. This allows the piano to have more stability and keeps it from rocking back & forth as a few other digital pianos can do. Also the C1 Air includes a slow-closing key cover so when Korg C1 Air cabinet & control panel picture you lower the cover to close over the keys, the key cover does just come crashing down on your fingers. It has a braking system that more slowly releases the cover to come down more gently which is a great feature. The piano closes up perfectly flat so it doesn't even look like a piano when the key cover is down...which is pretty cool. When the key cover is open it has enough mass/thickness to support a nice music light which can attach or clip on to the top of the key cover. A lot of digital pianos cannot do this so that's a nice feature when you want to light up your music in darker places. Speaking of darker places, I like the fact that the buttons on the piano control Korg C1 Air cabinet & control panel picture panel light up with red lights when they are depressed so you can easily see which function or sound you are using. The recording tracks also light up green when you are using a few different recording features on the piano. There are quite a few digital pianos that don't have light-up buttons or a digital display screen so you may not know what function you are using at the time. Another thing I appreciate about the C1 Air is that when you are playing instrument sounds (pianos, strings, organs, etc) and want to switch to a new sound while you are playing, the previous sound does not just drop out and stop playing. It keeps on sustaining until you press the keys down again and the new sound is heard. This is also true when you use the transpose key or are changing relatives volumes of layered instrument sounds while playing so the transitions are very smooth and uninterrupted. So this piano works well in that way which is especially important for live performance playing.

Korg C1 Air cabinet & control panel picture
One more thing about this piano worth mentioning is something I do not normally talk about in my reviews. The Japanese digital piano companies as well as the non-Japanese companies (Suzuki, Artesia, Kurzweil, etc) normally have their products manufactured in China, Indonesia, Malaysia, and other Asian countries because costs of doing business there are much lower than in Japan. Many years ago most Japanese designed products were also manufactured in Japan and the quality of those products made there were always much higher than products made in the other Asian countries. That has changed a lot now so that many items made in China, Indonesia, and other countries come out much better than before because those workers have better training and oversight. However, just about anything still made in Japan comes with higher quality and lower failure rates based on my experience with them. Korg is the only Japanese digital piano company that I know which actually still has their digital pianos made in Japan in the Korg digital piano factory which they have had for many years. That's pretty amazing considering the relatively low selling prices of their digital pianos and having them built in Japan with the high quality that they are known to have. So in my opinion that is definitely a "bonus" in terms of higher quality workmanship and longevity when it comes to Korg products as opposed to some other digital piano companies out there. The factory warranty on this model is 5 year parts and 1 year labor when registered on the Korg website after purchase of piano.

Korg C1 Air cabinet & control panel pictureAll in all, if you are considering a digital piano in this price range (around $1500US down to about $1000US) I would recommend you definitely consider the new Korg C1 Air as a very good choice, especially if your main goal is to play piano because that's what this piano is really all about. Although it does other things, has other functions, and allows you to play other excellent, usable instrument sounds, it's really all about the "piano playing experience" and not about having drum rhythms, hundreds of sounds, 16 tracks of recording, audio recording, interactive accompaniment tracks or apps, or other "bells & whistles." The C1 Air has arguably the best, most convincing responsive weighted and graded piano key action out of any brand in this price range which comes from their top-of-the-line Korg professional series Kronos stage pianos. Along with natural big stereo piano sound reproduction (you do not need any additional speakers or sub woofers) and dependable pedaling with great damper decay-sustain this piano gives you the immediate impression you are hearing and feeling a big grand piano with 2 very nice sampled grand pianos at your disposal along with their useful variations. *One final thing...for a number of weeks, the C1 Air has had an introductory price on the C1 Air from the Korg US factory headquarters of just $1049US* which is $350 off of the upcoming regular internet discount price of $1399US. The introductory price will end by the end of this month or when introductory supplies run out, whichever comes first, and then the price will be up to $1399US discount price and in fact is already that way on many dealer US web sites. A discount of $350 off  right now is a lot of money so if you think this sounds like the piano for you then you may want to act on it right away before the price goes up everywhere. Even when the price does go up, in my opinion it will still be a very competitive price given what the competition has in this price range and the features that Korg offers which they do not. *I can also help you save even more money off the $1049 introductory price if you act right away so please contact me before you by anything from anyone.

  1. Best review of this upgraded Korg DP. My only question is can you use different apps on this model,apps like recording,notation,and other types of apps such as those that have drum beats/ auto accompaniment.If it would support those other apps that would be awesome! How about it?

  2. Tim thank you so much for all the reviews, truly informative. I am a beginner in piano and I would love to learn. After long research I am between Yamaha Arius YDP 163, Roland F-140R, Kawai CN 17 and Korg C1 Air. Most interested I am for the last two. Which one out of the four would you choose? I am most interested about the acoustic piano sound and keys action authenticity. Thanks again, I will be looking forward to your thoughts.
