ABSTRACT:
A control system for an electronic music synthesizer includes a circuit responsive to the keying of a musical instrument for producing a binary coded signal. This signal is converted to an analog signal, for application to a music synthesizer. The analog voltage may be modified, for transposition or for portamento effects. The coding circuit may produce trigger and gate voltages for the synthesizer, whereby blowing of the musical instrument, if a wind instrument is employed, is not necessary. Alternatively, the trigger and gate pulses for the synthesizer may be developed from the output of the transducer coupled to the instrument.
