The Privia PX-350 represents a significant step in the continuing evolution of Casio's Privia digital piano line. Its combination of new 88-note keypad with Tri-Sensor Hammer Action and mighty AiR - Acoustic and Intelligent Resonator sound engine provides a new level of detail nuance and expression for a superior grand piano experience while maintaining the lightweight and stylish design that Privia is known for. Piano Sound With the PX-350 the award-winning grand piano sound in Privia has been dramatically improved. It utilizes more than three times the memory of the previous generation for a more natural piano tone. As mentioned above Casio’s new proprietary sound source “AiR” (Acoustic and intelligent Resonator) provides unmatched realism and detail. This engine provides seamless dynamics for a remarkably expressive and powerful performance. For further realism a new Damper Resonance simulator provides the rich sound of the strings when the sustain pedal is used. Key Action This special digital piano also features a redesigned 88 note Tri-sensor scaled hammer action keyboard. This new action features new simulated ebony and ivory textured keys for a more incredible feel and its three sensors capture the dynamics of a performance with unparalleled speed and accuracy. To further enhance the experience the action and the sound engine take into consideration the speed at which different-sized hammers move inside an acoustic grand relative to the velocity at which the keys are pressed. This timing nuance provides the ultimate key to your and your audience's sound experience. Powerful Features The PX-350 has a total of 250 instrument tones built-in. Strings organs electric pianos brass drums bass and more and with its registration capability you can store your favorite splits and layers for live performance use.
