Sound Technology

Unprecedented Natural Reproduction of the Rich Expressive Power and Resonance of an Acoustic Piano

Multi-dimensional Morphing AiR Sound Source

The characteristics of CASIO’s newly developed Multi-dimensional Morphing AiR* Sound Source reflect thorough attention to detail in expressing the rich, resonating tones inherent to the piano. The capacity of the installed memory has been expanded to achieve a longer sampling duration and enhanced waveform data quality. The temporal changes in tone that create sound you would expect only from a piano, beginning with the initial sound and leading into a beautiful extension until the sound eventually vanishes, are reproduced naturally.

AiR = Acoustic and Intelligent Resonator

Keyboard System

Natural Playing Feel Approaching That of a Grand Piano Firm Touch That Converts the Player’s Thoughts into Sound

Tri-sensor Scaled Hammer Action Keyboard II, with a grand piano’s unique sounding timing

The difference between the sound structures of a grand piano and a digital piano appears as a difference in timing, from the moment the instrument is played until the sound is audible. The new Tri-sensor Scaled Hammer Action Keyboard II responds by incorporating a system with three sensors that detect touches of the keys sequentially.

Simulated ebony and ivory keys with optimal fingertip fit for playing ease

The Simulated ebony and ivory keys offers the luxurious feel and texture as well as the smooth touch of a grand piano keyboard. The minutely detailed crimp surface finish inhibits finger slippage due to sweat and gives the sensation of a perfect fingertip fit, even when playing for extended periods.

An unprecedented evolution of the digital piano

Damper Resonance achieving a more naturally beautiful resonance than a pedal

The deep, beautiful resonance resulting from the use of a damper pedal is also reproduced naturally by a stereo resonance simulator installed on all 88 keys, an approach that differs from conventional simulated reproduction employing effect processing. The attention to detail goes so far as to simulate the resonance created by the lifting of the dampers themselves when the pedal is pressed.

Concert Play

High-quality audio data recordings of 10 live orchestra performances are installed. Pianists can play along with the recordings and enjoy the feeling of participating in a magnificent performance.
