ABSTRACT:
An electronic musical instrument having combined monophonic and polyphonic sound producing capabilities includes a keyboard simultaneously operating a monophonic tone signal generating circuit and a polyphonic tone signal generating circuit. The tone signals produced by the tone generating circuits are combined and coupled through a single signal processing stage and therefrom to an output speaker. A gate signal for enabling the monophonic tone signal generating circuit and for operating the signal processing stage is derived at the output of a detector circuit which is responsive to the presence of an audio output from the polyphonic tone signal generating circuit.
