Piano Sound:

The grand piano sounds in the AP-420 deliver an unprecedented level of realism and expression. Four dynamic levels of stereo piano samples are integrated with Casio's proprietary Linear Morphing System, for a grand piano sound with seamless transitions and a superior dynamic range. For added realism, the AP-420 simulates the sound of open strings when the dampers are raised by the pedal using Acoustic Resonance DSP.

Ivory Touch:

The new AP-420 features a new Tri-Sensor 88-note scaled hammer action keyboard. Casio's superior engineering has resulted in an authentic piano touch that captures every detail and nuance of your performance. This scaled hammer action provides the weight, feel and resistance of a grand piano without the need for tuning or regular maintenance of an acoustic instrument.

Education Features:

The AP-420 features a total of 16 built-in tones, with the ability to layer two sounds or split the keyboard to allow a bass sound in the left hand. It has a built-in library of 60 songs that can be practiced at any tempo utilizing the dual headphone outputs or the powerful 20W per side speaker system. Celviano's Duet Mode allows student and teacher to practice at the keyboard simultaneously.

Advanced Technology:

To complete the piano experience, the AP-420 features 128 notes of polyphony, enough horsepower to the most demanding musical passages and the ability to layer sounds and use the damper pedal without worry of dropped notes. In addition the AP-420 can load additional songs through the SD card slot and can connect effortlessly to your computer via USB without the need to install drivers.
