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 large number of tones utilizing channel assignment technology. A plurality of tones to constitute a chord are normally produced simultaneously by using plural channels, but when a duet mode is selected to automatically add a duet note to a melody note, the chord constituent tones are produced in succession as a broken chord utilizing only a single channel, thus leaving another channel available for production of the duet note. This eliminates the need to provide an additional tone production channel for the duet note. |
