ABSTRACT:
A channel assigning system which divides musical tone generating channels into a plurality of channel division areas and assigns musical tone generating channels of each channel division area to musical tones, in an ascending order of a value of a weighting factor corresponding to each musical tone generating channel, by searching for a musical tone channel corresponding to the smallest value of the weighting factor. Alternatively, the channel assigning system assigns musical tones in a descending order of a value of a weighting factor corresponding to each musical tone generating channel, by searching for a musical tone channel corresponding to the largest value of the weighting factor. Therefore, even if a performance is effected by quickly sounding musical tones in succession, and musical tone generating channels of a channel division area are assigned to the musical tones one after another, a performance of musical tones corresponding to musical tone generating channels of another channel division area is not affected and a radiation of musical tones is not stopped while a corresponding key is being pressed down.
