Abstract
When a desired rhythm is selected by a rhythm key group, corresponding rhythm data is set in a rhythm register in a CPU. Meanwhile, accompaniment pattern data is set in bass, backing and arpeggio registers by operation of corresponding bass, backing and arpeggio switches. The data set in the registers are supplied as address data to an arpeggio memory section, a backing memory section and a base memory section, so that corresponding rhythm data, tone color data and accompaniment data are read out.
