Electronic musical instrument and a method of dynamic channel assignment for solo and non-solo tones

摘要

An electronic musical instrument having a plurality of tone generation channels includes a solo tone channel assignment means and a non-solo tone channel assignment means. The solo tone channel assignment means preferentially operates to assign a solo tone to be generated to an unoccupied one of the plurality of tone generation channels. The assigned channel number is stored in a solo tone channel information memory. The non-solo tone assignment means looks up the solo tone channel information memory upon checking unoccupied channel information, and assigns tone information to an unoccupied channel excluding the channel number recorded in that memory. A solo tone is dynamically assigned to an unoccupied channel. That assigned channel is reserved without being assigned as a non-solo tone channel, and the solo and non-solo tones do not compete in channel assignment.
