Abstract
An electronic musical instrument is of a type in which tones are produced by a limited number of tone production channels which are efficiently used for a larger number of tones utilizing channel assignment technology. Normally, three of the channels are exclusively occupied for production of three tones to constitute a triad chord. But at time a bass tone is to be produced, the specific one of the three channels is compulsively used for production of the bass tone, giving up exclusivity for production of the chord tone. This eliminates the need of providing an additional channel for the bass tone production.
