Abstract

A music generator having a memory unit to store time and tone data of the selected song, which are read out successively from the memory unit in response to address signals applied to the memory unit by an address counter. The time data are sent to a latch, and the tone data are sent to a programmable counter and converted into a waveform by a wave shaping circuit. A tempo generator is electrically connected to, and actuates, a timing generator. The timing generator sends clock signals to the multiplexer when playing the selected song. Depending on the time data stored in the latch, the multiplexer determines and decides whether or not to actuate the address counter for requesting for the next tone data stored in the memory unit.
