Claims
- 1. A musical instrument comprising:
- an actuator which generates a plurality of actuation 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, said stored musical score comprising 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 by said user in said musical score;
- a video display unit;
- a digital processing means controlling said audio synthesizer and said video display unit,
- said digital processing means receiving said plurality of actuation signals from said actuator and generating a sequence of control signals therefrom,
- said digital processing means programmed to map the plurality of actuation signals from said actuator to a corresponding sub-sequence of lead notes from among said sequence of lead notes,
- said digital processing means programmed to produce the sequence of control signals from the sub-sequence of lead notes, said sequence of control signals causing said synthesizer to generate sounds representing the sub-sequence of lead notes,
- said digital processing means programmed to display on said video display unit a trace of markers as a function of time, wherein each of the markers within said trace of markers indicates a time at which the user is supposed to cause said actuator to generate one of the actuation signals of said plurality of actuation signals in order to cause the audio synthesizer to play a corresponding one of the sequence of lead notes of said musical score, said trace of markers representing a period of time extending from before an actual elapsed time until after the actual elapsed time, the actual elapsed time being measured from a start of the musical score, and
- said digital processing means programmed to display on said video display unit an indicator marking a location of the actual elapsed time within said trace of markers and thereby indicating where the user is presently supposed to be within the musical score.
- 2. The musical instrument of claim 1 wherein said digital processing means is also programmed to generate on said video display a second trace next to said trace of markers indicating when the user actually caused said actuator to generate each of the actuation signals of said plurality of actuation signals and thereby indicating when the lead notes of said sub-sequence of lead notes are actually played by said synthesizer relative to when they are supposed to be played as indicated by said trace of markers.
- 3. The musical instrument of claim 1 wherein said trace of markers is a sequence of pulses each of which corresponds in time to when the user is supposed to cause said actuator to generate one of the actuation signals of said plurality of actuation signals so as to cause said synthesizer to play an associated lead note.
- 4. The musical instrument of claim 3 wherein the pulses of said sequence of pulses vary in amplitude and wherein the amplitude of any given pulse indicates a relative intensity with which the user should play an associated lead note on said actuator.
- 5. The musical instrument of claim 3 wherein said actuator is a multi-element actuator and said sequence of pulses includes pulses having positive polarity and pulses having negative polarity, the polarity indicating a direction in which a chord is to be played on said multi-element actuator.
- 6. The musical instrument of claim 2 wherein said second trace is a sequence of pulses each of which corresponds in time to when the user actually caused said actuator to generate the actuation signals of said plurality of actuation signals.
- 7. The musical instrument of claim 2 wherein said trace of markers is a sequence of pulses each of which corresponds in time to when the user is supposed to cause said actuator to generate one of the actuation signals of said plurality of actuation signals so as to cause said synthesizer to play an associated lead note.
- 8. The musical instrument of claim 7 wherein the pulses of said sequence of pulses vary in amplitude and wherein the amplitude of any given pulse indicates a relative intensity with which the user should play an associated lead note on said actuator.
- 9. The musical instrument of claim 7 wherein said actuator is a multi-element actuator and said sequence of pulses includes pulses having positive polarity and pulses having negative polarity, the polarity indicating a direction in which a chord is to be played on said multi-element actuator.
