VRM physical modeling—the distinctive reverberation generated by the entire body of a concert grand piano
In a grand piano, sound resonates throughout the body of the instrument, producing a rich reverberation that envelops the listener in sound. This phenomena is reproduced perfectly in the Clavinova through enhanced Virtual Resonance Modeling (VRM). The original VRM calculates the various states of the strings for each of the 88 notes on the keyboard, from one instant to the next, and timing and depth of damper pedals pressed. The enhanced VRM now also calculates aliquot resonance in the upper octaves, and the full resonance of the soundboard, rim, and frame. This technology allows for vivid, bright, richly-varied expression that reflects the limitless number of factors inherent in piano performance.
Counterweights are embedded in the keys of a grand piano to balance the weight of the hammers and offer more precise control when playing delicately at low volumes. The Clavinova features carefully adjusted counterweights for improved playability when playing pianissimo with a light touch, and better key return in rapid passages. The keyboard of the Clavinova has been fine-tuned to offer optimal balance, emphasizing its superb playability and grand piano response.
Drawing from its experience in building both acoustic pianos and high-end speakers, the CLP-685 speaker cones use pulp from the same spruce wood used to make acoustic piano soundboards. This results in a more natural, piano-like attack to the sound.
