The Casio PX130 digital keyboard grand piano sounds deliver an unprecedented level of realism and expression. 4 dynamic layers of stereo piano samples are integrated with Casio proprietary Linear Morphing System, resulting in a grand piano sound with seamless transitions and a superior dynamic range. For added realism, the PX-130 simulates the sound of the open strings when the dampers are raised by the pedal using Acoustic Resonance DSP. The PX-130 also has 128-note polyphony, enough horsepower for the most demanding musical passages, and the ability to layer sounds and use the damper pedal without worry of dropped notes. The result is a grand piano experience that is unmatched at any price. please visit our website at http://www.mahkotamusic.com
