The Casio PX-870 Console Digital Piano award-winning AiR Sound Source includes a new four-layer stereo grand piano that comes alive with a realistic damper resonance that simulates the entire body of the instrument, not just the strings.  The piano also includes key action sounds, key off simulation, adjustable hammer response and a lid simulator with four positions. 

The PX-870 also includes string resonance, which exposes the sympathetic harmonic relationships between vibrating strings.  Along with adding to the subtle beauty of the sound, this adds authenticity when playing works by Debussy, Ravel, and others who wrote with string resonance in mind. 

The PX-870 features a variety of 19 instrument Tones, with the ability to layer and split them as needed. With a generous 256 notes of polyphony, even the most complex performances will sound perfectly natural.

Realistic piano sound with AiR

To reproduce the sound of the finest acoustic grand pianos, the Privia PX-870 features Casio's proprietary AiR (Acoustic and intelligent Resonator) processor. Accessing more than three times the memory of the previous generation, the AiR processor utilizes grand piano samples recorded at four dynamic levels of sampling to deliver grand piano sounds with long natural decays and remarkable expression. To further the grand piano experience, AiR adds realism by simulating the sound of the open strings when the dampers are raised by the pedal.

Sound Projection system fills the room with sound

At Sweetwater, we're impressed by the acoustics of the Privia PX-870, thanks to its Sound Projection system. This powerful 40-watt, 4-speaker system fills the room with rich, detailed sound. Best of all, the sound radiates from various places on the PX-870's cabinet, much like a traditional grand piano. Beyond that, you'll enjoy a balanced sound across the entire frequency range, at any listening volume, by virtue of this digital piano's Volume Sync EQ.

Scaled hammer action provides authentic piano feel

You'll deliver an expressive performance, thanks to the Privia PX-870's Tri-Sensor II Scaled Hammer Action piano keys, which are accurately scaled across the entire key range. Beyond that, simulated ebony and ivory textures provide an authentic touch. The PX-870's touch sensitivity is adjustable, allowing you to tailor it to your playing style, while its customizable hammer response accurately reproduces the delay between when a key is struck and a note is produced.
