This exclusive bundle includes a Casio Privia PX-150 88-Key Digital Piano, Samson HP10 Headphones (a $30 value), a Hal Leonard instructional book (a $15 value), and an Austin Bazaar polishing cloth (a $5 value). The Casio PX-150 combines a new keyboard action and a powerful new sound engine to provide a new level of detail, nuance and expression for a superior grand piano experience in the lightweight and stylish design for which Privia is known. The award-winning grand piano sound in Privia has been dramatically improved. The new PX-150 utilizes more than three times the memory of the previous generation for a more natural piano tone. In addition, 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. Casio"s PX-150 also features a new redesigned 88-note tri-sensor scaled hammer action keyboard. This new action features new simulated Ebony and Ivory textured keys for an incredible feel, while the 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 acoustic grand relative to velocity the keys are pressed, this timing nuance provides the ultimate key to sound experience. In addition to grand piano, Casio"s PX-150 digital piano has many other instrument tones including strings, organs, electric pianos, and bass. The PX-150 provides split and layer capability allowing you to play bass in your left hand and have two layered tones in your right. The Duet mode of this digital piano allows the keyboard to be split into two equal ranges, so that student and teacher can play simultaneously.
