The Touch of a Grand Piano: Grand Feel III wooden key action
- Embracing many of the long-established principles associated with an acoustic piano, the Grand Feel III keyboard action utilised by the CA901 combines realistic materials, motion, and mechanism to recreate the exceptional touch of the finest concert grand pianos.
All eighty-eight black and white keys are crafted entirely from long pieces of wood, with finely textured ivory and ebony-like surfaces applied to absorb moisture and assist control. Each wooden key pivots smoothly on a balance pin – the ends rising and falling to replicate the familiar ‘seesaw’ motion of an acoustic piano action. When pressed, the back of the key lifts, triggering a grade-weighted hammer to strike a pressure switch. The amount of force applied to this switch is then measured, and the corresponding note played with authentic tonal character and volume.
-
88-key Graded Counterweights
- In addition to grade-weighted hammers, the Grand Feel III action also features metal counterweights, attached beneath each key, and graded across the length of the keyboard.As with an acoustic piano, these additional weights help to balance the touch of the keyboard during pianissimo passages, while providing a feeling of greater substance and solidity when playing with force.
-
Ivory & Ebony Touch key surfaces
- The exceptional CA901 features Kawai’s highly regarded Ivory Touch white key surfaces as standard. This finely textured material gently absorbs fingertip perspiration and oils to assist playing control, and possesses a natural, matte finish that is smooth but not slippery.To complement these premium white keys, Kawai has also developed Ebony Touch, a special black key material that reproduces the finely-textured grain and rich lustre of real ebony wood. The result is a keyboard surface that looks and feels as luxurious as some of the world’s finest grand pianos, inspiring musicians of all levels to become better pianists.

The Sound of a Grand Piano: Shigeru Kawai SK-EX
- Eponymously named after the company’s second president, the Shigeru Kawai range of luxury grand pianos were conceived as the next step in evolving the art of the piano. Each world-class instrument is hand-crafted by experienced piano artisans, using the finest available materials to ensure optimum touch, tone, and artistic expression.Widely regarded as ‘the premier piano of Japan’, the flagship SK-EX grand piano graces the stages of concert halls and musical institutions around the globe, receiving universal acclaim for its tonal clarity and exceptional dynamic range. The magnificent tone of the SK-EX is at the heart of the CA901, with the latest model featuring two distinctive recreations of this peerless instrument.
-
Harmonic Imaging XL sound engine
- Accompanying the dedicated SK-EX Rendering pianos, the CA901 also features the flexible Harmonic Imaging XL sound engine, which offers a broader selection of instrument voices, and the ability to combine sounds. Harmonic Imaging XL also showcases a selection of alternative acoustic pianos captured with full 88-key stereo sampling.
- The Kawai EX full concert grand piano has frequently been selected by professional pianists in such prestigious events as the Tchaikovsky and Rubinstein international piano competitions, while the Shigeru Kawai SK-5 chamber grand and Kawai K-60 upright allow performers to enjoy the contrasting tonal characteristics of various different piano sizes and voicing configurations.
-
Premium speaker drivers
- As the flagship model of the Concert Artist series, the CA901 features a powerful hybrid speaker configuration that combines premium driver units with Kawai’s highly-regarded soundboard speaker technology, delivering crystal clear treble frequencies and warm, resonant bass.
- In addition to premium audio processing and amplification hardware, the CA901 also features a high specification speaker system, developed by audio specialists. Premium speaker drivers were selected for their flat frequency response and ultra-low distortion characteristics, ensuring the most accurate reproduction of the original Shigeru Kawai SK-EX grand piano, while diffuser panels help to disperse the sound more evenly.
-
360° Speaker Diffusers
- In addition to utilising premium driver units, the CA901 top-mounted speakers also feature custom-engineered diffuser panels, which help to expand the pianos’ tonal projection in all directions.These additional components create a 360° sound field around the instrument, ensuring a natural piano sound for both the player, and those listening elsewhere in the room.
-
TwinDrive Soundboard Speaker System
- Complementing the premium quality drivers, the CA901 also incorporates the latest version of Kawai’s highly-regarded soundboard speaker system. This unique audio technology embraces the rich, harmonic qualities of wood by using transducers to channel sound energy onto a large soundboard, in order to produce a more natural, organic tone. Long wooden ribs securely attached to the soundboard further broaden the frequency range and volume of the resonating sound, resulting in a remarkably authentic playing experience that immerses the performer, and faithfully reproduces the tonal ambience of an acoustic piano.
-
The Variety of a Digital Piano: Convenience & Flexibility
- Complementing the instrument’s class-leading Grand Feel III keyboard action and stunning SK-EX Rendering piano sound engine, the CA901 also offers a strong selection of digital features that further enhance one’s musical enjoyment.Full Bluetooth® V5 connectivity and USB audio record/playback allows musicians to extend the functionality of their piano, or play-along with their favourite artists, while the convenient metronome and integrated lesson functions, featuring classical etudes and Alfred course books, ensure that regular practise is both productive and engaging for aspiring pianists.
-
PianoRemote app
- The CA901 allows the user-friendly touchscreen interface to also be accessed via the dedicated PianoRemote app for iOS and supported Android devices. The app connects to the piano wirelessly via the Concert Artists’ integrated Bluetooth, providing an effortless way to change sounds, or enjoy the vast array of built-in music content from the comfort of an armchair.
-
Rich sound selection
- Supplementing the beautiful acoustic piano voices, the CA701 also features an excellent selection of additional instruments, ranging from electric pianos and drawbar or church organs, to strings, human choirs, and synth pads, inviting musicians to add greater variety to their performances.Furthermore, the Dual playing mode also allows two different sounds, such as grand piano and strings, to be layered together for a richer, more luscious tone, while the Split and Four Hands modes divide the keyboard into two independent sections with separate sounds for each. The volume balances and other settings for each playing mode can also be easily adjusted using the instrument’s intuitive touchscreen interface.
-
Flexible USB connectivity
- In addition to wireless functionality, the Concert Artist is also equipped with USB ports that allow the instrument to be connected directly to a computer for MIDI use, or to load and save data to USB memory devices.This latter USB to Device functionality allows recorder songs stored within internal memory to be safely preserved on USB flash drives, or for standard MIDI files (SMF) downloaded from the internet to be played back and enjoyed using the instrument’s exquisite Harmonic Imaging XL sounds without additional hardware or cables.
-
MP3/WAV Playback & Record
- USB memory devices can also be used to play back MP3 or WAV audio files, allowing musicians to learn the chords or melody for a new piece, or simply enjoy playing along with their favourite songs. It is even possible to record entire performances (including external Line In and Bluetooth audio sources) as MP3 or WAV audio files for emailing to family and friends, or casual listening away from the piano.
-
Built-in lesson & finger exercises
- The CA901’s convenient lesson function allows aspiring pianists to learn piano with classical Czerny, Burgmüller, Beyer, Bach, Beethoven, and Chopin etudes, or a collection of songs from the popular Alfred’s Basic, Adult, and Premier course books.
- With a strong emphasis on acoustic piano realism, the Concert Artist also features traditional finger exercises, scales, and warm-up drills, and includes companion books for all classical scores to further aid one’s piano development.

* Included score books dependent on market location.
* Alfred lesson books sold seperately.

The CA901 is available in three attractive cabinet finishes: Premium Rosewood, Premium Satin Black, and Premium Satin White, allowing musicians to coordinate their piano with a range of modern interiors.
