Abstract
An apparatus and method of controlling note velocity within an electronically controlled player piano in response to the analog characteristics (level, strength, amplitude, etc.) of a received audio signal encoded with a MIDI (or similar) note stream. The invention allows conventional audio playback devices to be utilized as a source for MIDI information which drives the actuation of the keys of the player piano.
