Disklavier

thumb|250px|Yamaha Disklavier Pro S6 Grand Piano Disklavier is a brand of reproducing pianos manufactured by Yamaha Corporation. The first Disklavier was introduced in the United States in 1987.

The typical Disklavier is a real acoustic piano outfitted with electronic sensors for recording and electromechanical solenoids for player piano-style playback. Sensors record the movements of the keys, hammers, and pedals during a performance, and the system saves the performance data as a Standard MIDI File (SMF). On playback, the solenoids move the keys and pedals and thus reproduce the original performance.
