Articulating this beautiful SK-EX sound is the brand new Grand Feel III wooden-key action, which draws upon Kawai’s 90+ years of acoustic piano craftsmanship to provide an exceptionally realistic playing experience. As with a grand piano, all of the Grand Feel III action’s eighty-eight black and white keys are crafted entirely from long pieces of wood, and pivot on a central balance pin with a smooth, seesaw-like motion. This natural movement throws grade-weighted metal hammers located at the back of the keyboard, with their individual velocities precisely measured using triple-sensor technology for improved responsiveness and realism.
The Grand Feel III action’s extended wooden keys also boast an extra-long pivot length – matching that of a Kawai acoustic grand piano. This provides a more consistent touch weight when playing towards the rear of the keyboard, while additional counterweights placed below each key help to further balance the weight of the action during pianissimo passages. Finally, the Grand Feel III keyboard action also features Kawai’s Ebony & Ivory Touch key surfaces that gently absorb moisture to assist playing control, and possess a natural, matte finish that is smooth, but not slippery.
Extra-long key length, Extra-long pivot length - In addition to featuring extended, fully wooden keys, 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 minimizing 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.
Triple sensor key detection - The Grand Feel III keyboard action also features 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.
Ivory & Ebony Touch key surfaces - The exceptional CA79 and CA99 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 luster 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.
Let-off Simulation - As the most authentic digital piano keyboard action, Grand Feel III 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.
In addition, the Grand Feel III action supports playing notes from the let-off point (sometimes referred to as playing ‘off the jack’), allowing the most advanced piano techniques to be performed.
