Abstract:
1. A source dependent instrument signal processing and signal generation system for a source dependent instrument which produces musical sounds, comprising: an input interface for generating an input signal in response to and representative of an input event including an audible input event occurring in an environment external to the source dependent instrument signal processing and signal generation system and instrument and having input signal parameters, the audible input event comprising a quasi-indeterminate sound generated by at least one of (i) another sound source other than sound outputted by the source dependent instrument signal processing and signal generation system, and (ii) a plurality of people, and the input signal parameters including an audio parameter of the plurality of people; analysis elements for receiving and analyzing the input signal to determine parameters thereof; at least one function generator and at least one secondary audio signal generator for receiving the input signal from the analysis elements and the function generators outputting a control function signal based on and in response to the input signal and the secondary audio signal generators outputting a secondary audio signal based on and in response to the input signal; an audio signal processer receiving the input signal and at least one of the control function signal and the secondary audio signal and responsive thereto for at least one of re-synthesizing the input signal and shifting parameters of the input signal to provide a first output signal having output parameters shifted in relation to and based on and responsive to the input signal parameters; an output stage responsive to the first output signal from the processer for generating a second output signal responsive to the first output signal; and a controller for adjusting at least one of the re-synthesizing and parameter shifting performed by the processor, further comprising a feedback loop for receiving the second output signal and feeding the first output signal back to the environment, and wherein the controller controls the feedback, wherein the environment is external to the source dependent instrument and the source dependant signal processing and signal generation system.
