ABSTRACT:
An electronic musical instrument having selectable monaural, stereo and multiple channel musical performance capability is disclosed which includes a performance data generating device; tone signal generating systems; sound producing systems; a mode indicating device; a selection device; and a distribution device. The tone signal generating systems generate musical tone signals based on performance data generated by the performance data generating device. The sound producing systems produce musical sounds based based on the musical tone signals. The selection device allocates performance data to a single musical tone signal generating system when the mode indicated by the mode indicating device is the first mode. The selection device allocates performance data to plural musical tone generating systems when the mode indicated by the mode indicating means is the second mode. The distribution device supplies to one or more musical sound producing systems the musical tone signal output from the single musical tone generating system when the mode indicated by the mode indicating device is the first mode. The distribution device supplies to at least two musical sound producing systems the musical tone signals output from the respective musical tone generating systems when the mode indicated by the mode indicating device is the second mode.
