With an emphasis on piano-focussed authenticity, the CA401 utilises the superb Grand Feel Compact wooden-key keyboard action. As its name suggest, the GF Compact action has been designed to reproduce the authentic touch weight characteristics of the industry-leading Grand Feel keyboard actions, within a smaller form factor.
This action retains the long wooden keysticks used for all 88 black and white keys, and the familiar ‘seesaw’ mechanism employed by acoustic grand piano actions for centuries. However, despite its smaller unit size, GF Compact features an extended key pivot length, providing a more consistent touch weight when playing towards the rear of the keyboard. This crucial detail, along with various other acoustic piano-like characteristics, ensures the CA401 delivers the most realistic playing experience in its class.
This video outlines the history of Kawai’s wooden key keyboard actions, and examines how the latest generation Grand Feel actions incorporate characteristics from acoustic grand pianos.
The video also explains the importance of ‘seesaw’ key movement, and other meticulous details that replicate the feel of playing an acoustic grand piano.
In addition to grade-weighted hammers, the Grand Feel Compact keyboard action also features counterweights attached towards the front of the bass keys.
As with an acoustic piano, these finely balanced weights help to lighten the touch of the keyboard during pianissimo passages, while adding a feel of greater substance when playing with force.
The Grand Feel Compact keyboard action utilises an accurate triple-sensor key detection system for enhanced playing realism.
The added third sensor improves responsiveness when playing the same key repeatedly, and unlike conventional two sensor keyboard actions found in many digital pianos, allows the sound of a single note to be gradually ‘layered’ without the previous tone being lost.
In addition, Kawai’s action technology also monitors the speed at which each key is lifted, influencing the release character of piano sounds, and providing a greater range of expression between staccato and legato playing.
The impressive CA401 features Kawai’s highly regarded Ivory Touch 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.
Furthermore, this moisture is absorbed without dirt or grease permeating the surface, allowing the keytops to be wiped clean easily using just a damp cloth.
As the most authentic digital piano keyboard action in its class, Grand Feel Compact even reproduces the ‘let-off’ characteristic of acoustic piano actions.
This subtle ‘notch’ sensation can be felt when playing the keys of a grand piano very gently, and may be used by experienced pianists to aid control when playing pianissimo passages.
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 CA401, with this new model featuring the latest SK-EX Competition Grand recreation of this peerless instrument.
The brand new SK-EX Competition Grand captures the sound of the latest generation SK-EX-L instruments, that in recent years have achieved success at the Chopin, Hamamatsu, and Sendai international piano competitions.
This piano sound possesses a brilliant, clear tonal character, with a distinctive thick attack, and is specifically recorded from the pianist’s position for the ultimate performance experience.
The rich, expressive sound of the SK-EX concert grand piano is at the heart of the CA401, with all eighty-eight keys of this world-class instrument painstakingly recorded, meticulously analysed, and accurately reproduced as high-fidelity digital waveforms.
Recording each key individually in this way – as opposed to stretching the same tone over several different notes – preserves the grand pianos’ unique harmonic character, and guarantees that the sound heard when playing any one of the CA401’s wooden keys is a faithful representation of the original acoustic source.
When playing a fine piano, the amount of pressure applied to the keyboard affects not only the volume of the sound produced, but also the unique tonal character of each note. Therefore, in order to construct a realistic acoustic portrait of each grand piano, not only is each key recorded individually, but also at a wide variety of different volumes, ranging from gentle pianissimo to thunderous fortissimo.
The CA401 offers a highly detailed acoustic portrait, employing Kawai’s proprietary Harmonic Imaging XL sampling technology to ensure smooth tonal transitions across the keyboard and throughout the entire dynamic range.
Alongside the classically voiced SK-EX and EX grand piano sounds, the CA401 also showcases a selection of Jazz, Pop, and Modern variations suitable for a range of musical genres. A traditional Kawai upright piano sound is also included, for pieces that suggest a feeling of nostalgia, or call for a slightly more intimate tonal character.
The knowledge and skill of an experienced piano technician is essential to bring out the best of a fine acoustic piano. In addition to tuning each note, the technician also performs numerous regulation and voicing adjustments that allow the instrument to truly sing.
The CA401’s powerful Virtual Technician function simulates these refinements digitally, allowing discerning musicians to shape aspects of the selected piano’s character to suit their personal preferences.
Perform touch weight and voicing adjustments, regulate hammer and key release noises, and fine-tune string, damper, and cabinet resonances. It is even possible to adjust the precise tuning, volume, and character of individual notes – all in real-time.
Developed by Kawai R&D’s highly experienced audio engineering team, the CA401 features a redesigned motherboard and speaker system, and a brand new high quality power adapter. These components combine to deliver best-in-class audio quality, producing an extremely rich, clear sound with minimal distortion.
The CA401 motherboard and sound hardware is engineered for precise signal conversion and optimum sound quality. Advanced low-noise circuit designs and premium audio components combine to ensure crystal clear, high-fidelity sound with minimal distortion.
The CA401 boasts an impressive 4-speaker output system, with lower range frequencies delivered through the underside of the instrument, and mid and high frequencies projected outward via front-facing speakers. The result is a broad, resonating tone that closely mirrors the immersive sound field of a grand piano.
The CA401’s stereo speaker system delivers an impressive 40W of output, providing more than enough power to fill a medium-sized room with it's beautiful Shigeru Kawai grand piano sounds.
Moreover, when playing through speakers at a reduced volume setting (so as not to disturb family members), the CA401’s Low Volume Balance feature intelligently adjusts keyboard touch and piano tone characteristics, allowing pianissimo passages to be played smoothly and more naturally.
The CA401’s Spatial Headphone Sound (SHS) technology enhances the depth and realism of the instrument’s sound when listening through headphones or earphones. The player can select one of three different acoustic presets that adjust the spatial positioning of the sound, while also helping to reduce auditory fatigue when using earphones or headphones for extended periods of time.
In addition, the CA401 also allows players to select a variety of headphone types (Open, Semi-open, Closed, In-Ear, Canal, etc.) for an optimised listening experience.
Complementing the instrument’s class-leading Grand Feel Compact wooden-key keyboard action and Progressive Harmonic Imaging piano sounds, the CA401 also offers a variety of convenient digital features that further enhance one’s musical enjoyment.

The CA401’s convenient lesson function allows aspiring pianists to learn piano with classical Czerny, Burgmüller, Chopin, and Beyer etudes, or collections of songs from the popular Alfred’s Basic Piano course books.
The left and right hand parts of each etude/song can be practiced separately, using the adjustable metronome feature to perfect timing in difficult passages, before recording the completed piece for self-evaluation.
* Notated scores and Alfred lesson books sold separately.
Supplementing the beautiful acoustic piano voices, the CA401 also features a modest selection of additional sounds, 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, while the Four Hands mode divides the keyboard into two independent 44-key sections. This feature is particularly useful in learning environments, allowing teacher and student (or student and student) to play together at the same time using a single instrument.
Reinforcing the CA Series’ reputation as the most realistic digital pianos in their price range is Kawai’s Grand Feel Pedal System.
This unique feature accurately replicates the position and individual weighting of the damper, soft, and sostenuto pedals of a Shigeru Kawai SK-EX concert grand piano, ensuring that players master the proper pedalling technique required to perform on an acoustic piano.
The CA401’s modern cabinet incorporates a rounded topboard and tapered leg design, with minimalist toe blocks for additional stability. Its flat fascia and tall upper board give the instrument a traditional, upright piano-like quality, while at just over 48 centimetres deep, the CA401’s compact body is suitable for apartments and other narrow spaces.
The CA401 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.

The CA401’s broad music rest is engineered to accommodate the most ambitious musical works, with smoothly rounded edges and a sturdy base for supporting large score books.
As with a grand piano, the viewing angle of the instrument’s music rest can be adjusted to suit the performer’s playing position, or laid flat for convenience when notating scores or sketching musical ideas.
The CA401’s music rest base also incorporates score support pins, which can be raised to hold the pages of thicker score books securely in place.
The smooth, rounded edges and gently tapered design give the score support pins a high quality, premium feel, while their crystal-like transparent finish also helps to prevent obscuring the notation behind.
The CA401 features an easy to use control panel neatly embedded within the left cheekblock, with a high resolution OLED display providing information about the currently select sound, function, or setting.
Unlike other digital pianos in its class, the CA401's various sounds and functions are all selected directly from the control panel, without needing to press and hold buttons while remembering different key combinations. This helps to simplify operation, and ensures that the piano can be enjoyed by even the youngest members of the family.
