ABSTRACT:
An improved dual-tone electronic music generator provides a phase difference between a melody and a chord such that the melody codes converted from the melody and the chord codes converted from the chord can be stored into a memory in series. This arrangement can increase the memory usage efficiency, and can reduce both the chip size and the production cost.
