Description
The Sound of a Grand Piano
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 this new model featuring the latest SK-EX Competition Grand, capturing the sound of the latest generation SK-EX instruments that in recent years have achieved success at the Chopin, Hamamatsu and Sydney 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.
SK-EX Rendering Engine

Multi-channel Sampling

While digital pianos typically employ single-point stereo sampling, the SK-EX Rendering engine’s multi-channel sampling captures the sound from different points of the Shigeru Kawai concert grand.
This modern technique not only allows a broader range of tonal characteristics to be recorded and reproduced, but also improves the connection felt between the keyboard and piano sound, resulting in a more lively and authentic response to changes in dynamics.
Full Resonance Modelling

This naturally expressive Shigeru Kawai sound is further enriched by newly developed resonance algorithms, which physically model the complex tonal interactions produced by the strings, dampers, and various other parts of an acoustic piano.
Unlike other resonance simulations, SK-EX Rendering generates resonances for the damper pedal and all 88 keys progressively (i.e. in gradual amounts, not simply on or off), allowing the Concert Artist to behave – and therefore be controlled – more like an acoustic piano.
The Touch of a Grand Piano

Triple Sensor Key Detection
The three sensor key detection 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
Let-off Simulation
Regarded as the most authentic digital piano action in its class, Grand Feel III even reproduces the ‘let-off’ characteristic of acoustic piano actions.
Balance Pins
The GFIII action preserves the traditional ‘seesaw’ mechanism found in acoustic grand piano actions, along with the long wooden key sticks utilized for all 88 black and white keys. It incorporates an extended key pivot length to the balance pins, resulting in a consistent touch weight when playing towards the back of the keyboard. This essential feature, combined with other acoustic piano-like qualities, guarantees that the CA701 delivers the most authentic playing experience in its category.
Long Wooden Key Stick
With an emphasis on piano-focussed authenticity, the CA701 utilises the superb Grand Feel III wooden-key keyboard action. As its name suggests, the GF III action has been designed by drawing upon our 95+ years of piano building expertise to reproduce the authentic touch weight characteristics of our acoustic grand piano range.
Grand Feel keyboard actions also boast some of the longest key pivot lengths – matching that of a Kawai grand piano.
This extended key pivot length provides a more evenly balanced touch weight from the front to the rear of each key, allowing greater fluency and expressive control, while also minimising the need to readjust one’s technique when playing an acoustic grand piano.
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 Surface
The exceptional CA901 features Kawai’s highly regarded Ivory Touch white key surfaces as standard. This finely textured material gently assists 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.
