Abstract
An electronic musical instrument is of a channel assignment type and simultaneously produces a plurality of tones in automatic arpeggio performance. For that purpose, the instrument incorporates a plurality of automatic arpeggio performance channels. An automatic arpeggio performance is carried out in accordance with an arpeggio pattern. In order to simultaneously produce a plurality of automatic arpeggio tones, the instrument assigns respective arpeggio composing tones for the plural arpeggio performance channels by using an arpeggio pattern for one-tone production and a change pattern obtained by adding change information to the arpeggio pattern. Thus an automatic performance of polyphonic arpeggio is realized.
