Memory override system for programmed electronic synthesizer

摘要

A programmable electronic musical synthesizer includes a memory controlling a plurality of parameter circuits according to a selected group of stored parameter signals for producing a desired timbre of sound. A memory override system is responsive to manual operation of each of a plurality of control knobs for overriding a corresponding stored parameter signal and coupling an externally derived input signal to the associated parameter circuit. The memory override system thereby conveniently enables one or more selected parameter circuits of the synthesizer to be manually controlled by a performer while the other parameter circuits are simultaneously controlled from memory.
