Abstract

A musical instrument including an actuator which generates a plurality of signals in response to being played by a user; an audio synthesizer which generates audio tones in response to control signals; a memory storing a musical score for the actuator; a video display unit; and a digital processing means controlling the audio synthesizer and the video display unit. The stored musical score includes a sequence of lead notes each of which has an associated time stamp to identify a time at which it is supposed to be played in the musical score. The digital processing means is programmed to map the plurality of signals to a corresponding subsequence of lead notes from among the sequence of lead notes; it is programmed to produce a sequence of control signals from the subsequence of lead notes for causing the synthesizer to generate sounds representing the subsequence of lead notes; it is programmed to display on the video display unit a trace indicating when the lead notes of the sequence of lead notes are supposed to be played by the user as a function of time; and it is programmed to display relative to that trace an indicator marking where the user is supposed to be within the musical score as a function of an elapsed real time.
