Casio's proprietary sound source, AiR (Acoustic and intelligent Resonator) provides the grand piano sounds in the PX-160. Casio meticulously recorded the sound of a 9-foot concert grand at 4 dynamic levels. The AiR engine delivers this sound with seamless dynamics for a remarkably expressive and powerful performance. Damper Resonance is simulated by AiR for uncanny realism when the damper pedal is used.
