Unprecedented Natural Reproduction of the Rich Expressive Power and Resonance of an Acoustic Piano ! Weighted key stage piano and synthesiser. Casio developed its Multi-dimensional Morphing AiR Sound Source to seamlessly reproduce the natural changes in the tone, volume and timbre of a grand piano from the moment a note sounds, through its beautiful sustain, until it finally vanishes away. Even the length of the reverberation can be controlled like an acoustic piano by adjusting the force of the keystroke. Players can also control the sustain of beautifully resonating tones according to their performance styles by using the piano’s built-in String Resonance function, which simulates the distinct reverberations of all 88 keys of the keyboard, a function that reproduces the resonant effect of a damper pedal. Damper pedal and power supply included. with Gig bag
