Casio PX-870


The PX-870’s award-winning AiR Sound Source includes a new four-layer stereo grand piano which comes alive with realistic damper resonance, simulating 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 other composers 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, you can rest assured that even the most complex performances will sound perfectly natural.
