The versatility of the grand piano is made possible by its ability to alter tones in accordance with changes in the amount of pressure applied to the keys. Strong pressure produces a bright, hard tone, while lighter pressure results in a much gentler tone and these tonal variations provide the pianist with a rich palette of musical expression. CASIO digital pianos use multiple samples collected at various optimal key pressures from a world-famous brand concert grand piano. A CASIO-original Linear Morphing AIF Sound Source, which applies computer graphic morphing technology to notes, ensures seamless changes between the sampled sounds. This, in combination with a revolutionary filter circuit that controls changes in timbre enables seamless changes in tones of extremely delicate pianissimos all the up to powerful fortissimos. The result is a never-before-possible level of expressive richness that is virtually the same as what you hear from an acoustic grand.

The Acoustic Resonance system generates rich, beautiful resonance when the damper pedal is depressed. It reproduces the reverberation of neighboring strings that occurs within an acoustic grand.

True and smooth grand piano level key action is reproduced using the actual weight of the hammer, without relying at all on springs. This Tri-Sensor Scaled Hammer Action Keyboard uses a total of three sensors on both the keyboard side and the hammer side for outstanding playability of successive notes. Thanks to these sensors, following notes can start to sound even before the keys that played previous notes are fully released, creating a feel that is virtually the same as that of an acoustic grand. Of course, low notes play heavier and higher notes play lighter, also like a grand piano.
