ABSTRACT:
This electronic musical instrument has plural operation units respectively performing a predetermined basic waveform generation operation (e.g., frequency modulation operation) using a phase signal representing a pitch of a tone to be produced or a waveform signal generated by the operation unit. There is further provided a setting section for variably setting a combination of input and output connections between the respective operation units as freely as the performer desires. The input and output connections between the operation units are switched according to the set combination. An operation algorithm for tone synthesis is determined according to the combination of connections between the operation units set in this manner whereby a free tone synthesis as desired by the performer is realized. A display is provided for visually indicating the set combination of connections and a state of connection between the respective operation units is indicated as a graphic pattern on this display.
