Abstract
A music synthesizer has one or more sensors that generate a respective plurality of sensor signals, at least one of which is an audio frequency sensor signal. Electronic circuitry, such as a specialized circuit or a programmed digital signal processor or other microprocessor, implements a physical model. The electronic circuitry includes an excitation signal input port for continuously receiving the audio frequency sensor signal as well as a control signal port for continuously receiving a control signal corresponding to the audio frequency sensor signal. The-control signal can have much lower bandwidth than the audio frequency sensor signal. The electronic circuitry also includes circuitry for generating an audio frequency output signal in accordance with the physical model, utilizing the audio frequency sensor signal received via the excitation signal port as an excitation signal for stimulating the physical model, and using the received control signal to set at least one parameter that controls the generation of the audio frequency output signal. In some implementations, the music synthesizer will include a second sensor for generating a second control signal. The circuitry for generating the audio frequency output signal may include a variable length delay element whose effective delay length is controlled by at least one of the sensor signals.
