A new 4 layer stereo grand piano sound is delivers a natural, expressive and dynamic piano experience.

    Piano Sound

    The grand piano sounds in the AP-450 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-450 simulates the sound of open strings when the dampers are raised by the pedal using Acoustic Resonance DSP.

    Ebony and Ivory Textured Keys

    The new AP-450 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.

    The AP-450 features a total of 18 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-450 features 256 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.

This allows Celviano to be used with Mac or Windows computers without the need for downloading drivers.
