Superb sound and outstanding design that will enhance any room. KORG sets a new standard for the Digital Piano.

The C1 is a truly exceptional digital piano. With KORG’s unique history of musical instrument design and audio technology, the C1 offers levels of playability and versatility that will exceed the expectations of the most demanding pianist. From the very first note, the depth and clarity of sound that the C1 delivers from its compact, slim-line cabinet will astound both player and audience alike. The precisely-engineered keyboard provides a feel and response that has been designed to help the student develop a sound playing technique while responding fully to the demands of the more advanced player.

First and foremost, the KORG C1 is a superb piano, both as an exciting alternative to an acoustic instrument or in locations where a traditional instrument could not be used. It never needs tuning and can be used with headphones to avoid disturbing others.

Furthermore, a variety of additional features will inspire new levels of creativity in players of all abilities and enhance their enjoyment of music, including 30 superbly realistic instrument sounds, Bluetooth audio streaming and on-board recording. Designed and manufactured in Japan, the KORG C1 redefines the digital piano.

  • A choice of acoustic piano sounds

  • Digital recreation of true grand piano resonance

  • RH3 keyboard accurately simulates acoustic piano touch and response

  • Thirty high-quality voices

  • Newly developed amplification and speaker system

  • Contemporary design cabinet available in 3 color options

  • Bluetooth audio playback

  • The Stereo sound optimizer that gives presence to the sound when the headphones are used.

RH3 keyboard provides a great-feeling playing experience

The C1 features the real weighted hammer action 3 (RH3) keyboard that accurately simulates the playing experience of a grand piano, with a heavier playing feel in the lower register that becomes lighter as you move up the keyboard. It is extremely responsive, even when notes are repeated quickly, while the performer’s expressive dynamics are faithfully interpreted even in the most complex passages. Key touch control is also provided, with a choice of five levels of sensitivity (light, normal, heavy, stable, fixed) to specify how your playing dynamics are reflected by the sound produced.

Sophisticated and elegant design

While paying homage to the acoustic piano’s traditional form, a new design philosophy elevates the C1 above the bland, rectangular appearance of many digital pianos. The contemporary design features linear legs which accentuate the overall styling of the instrument and, at only 26 cm (10.24")* in depth, the C1 can be placed virtually anywhere. Keeping safety in mind, the cover uses a soft landing mechanism to ensure that it closes gently. The C1 is available in a black, white or brown wood finish to match the décor of your room. (*Excluding the anti-tip hardware)

Tradition and technology in harmony create a concert grand piano virtually anywhere
The sound of a piano changes significantly depending on how it is played. In order to provide this high level of expressive power from a digital piano, two concert grand pianos were selected by professional pianists, regulated and tuned by master technicians and sampled by KORG engineers. This complex process enables the C1 to simulate the experience of playing either a German grand or a Japanese grand, and were chosen to reflect a broad musical spectrum providing faithful recreations of dark, subtle and intense classical music through to bright and powerful jazz and pop music. The C1 gives you natural and satisfying grand piano performance at home, on stage or in the studio.

Damper Resonance

Both the German Grand Piano and the Japanese Grand Piano sounds realistically recreate the "damper resonance" effect produced by the sympathetic resonance of the strings in an acoustic piano when the damper pedal is held down.

Key-off Simulation

Key-off simulation recreates the sounds produced when the player’s fingers lift off the keys. The damper resonance effect and key-off simulation provide an even greater feeling of realism as you play!

Bluetooth audio support (C1 Air only)

Connect a Bluetooth device such as a smartphone to the C1 Air and enjoy playing the piano along with your stored music or other audio. When you are not playing the piano, you can use the C1 Air as a powerful Bluetooth speaker system.

* Depending on your region, the C1 Air Bluetooth-equipped model may not be available. Please contact your local KORG distributor for further information.

New speaker system delivers high output and great sound

The C1 features a specially designed speaker system that delivers the incredibly realistic sounds of the C1 pianos and other instrument voices in superb detail. High-quality speakers are powered by a 25W x 2 amplifier to deliver rich sound with depth and clarity. From rounded bass to brilliant highs, you will experience the nuanced, expressive power of a grand piano in your own home.

Enjoy 30 high-quality instruments sounds and studio effects

The German Grand piano characterized by brilliant highs and rounded bass is one of richness and power. The Japanese Grand piano is characterized by its dynamic sound and is frequently used for a wide range of music genres, from classical to jazz and pop.

In addition to a choice of these acoustic piano sounds, the C1 also offers electric piano sounds, organ, clav, vibraphone, acoustic guitar, strings and more, giving you a total of 30 richly expressive sounds. Three high-quality effects are also available: brilliance, reverb, and chorus. Optimal effects are preset for each of the built-in sounds, so all you need to do is select a sound and enjoy playing immediately with the ideal settings.

Equipped with three pedals as standard with half-pedaling feature

The pedals are an essential element of piano performance, and the C1 is equipped with the full complement of three pedals found on a grand piano: damper, soft and sostenuto. The damper and soft pedals also feature half-pedaling for even more detailed expression.

A variety of keyboard layout options

Simply by pressing one button, you can apply a bass sound to the lower register of the keyboard. Play piano with your right hand and bass with your left to instantly enjoy jazz performance styles. By pressing two of the tone buttons simultaneously, you can easily layer two sounds together. For example, layer piano and strings to play with a rich piano and orchestra combination. There’s also a partner mode that enables you to divide the piano keyboard into two identical sections on left and right, each with their own damper pedal. This is a great way for teacher and pupil to play duets or copy and practice during lessons.

Forty piano songs with helpful features for practicing

In addition to ten demonstration songs that showcase the different sounds of the C1, there are also 40 built-in piano songs. To help you learn, you can control the tempo, play back the right-hand and left-hand parts separately, and use A-B repeat to practice more complex sections.

Two-track song recorder to instantly record your performance

Two-track digital recording is instantly available to help you analyze or archive your performances. You can record each hand separately or record an additional track onto a previously-recorded song. Playback tempo can be adjusted and up to 99 user songs can be saved in the C1.

The Stereo sound optimizer that gives presence to the sound when the headphones are used

This gives presence to the sound that is reproduced, as if playing an acoustic piano, even when headphones are used. You can experience comfort even with a long performance.

The salesman was extremely helpful giving impartial advice and pros and cons for each piano.

Casio PX870WH Piano


I had very specific requirements due to the size and colour of piano I was looking for, meaning in the end only one piano model was suitable. I phoned over 15 stores nationwide trying to find this model however no store had any stock due to the effects of covid meaning demand had outstripped supply. I found Keysound on the internet and thought I would give them a try and I found the guys extremely friendly and rather than simply saying they had no stock, they worked hard following our phone call by making some enquiries to try and get me the piano I was looking for. After managing to obtain one, it arrived within a day of posting and it has slotted in perfectly and is very popular with the family. I would highly recommend this company, very friendly over the phone, great to do business with and extremely knowledgeable.
