PURPOSE: To miniaturize a hardware constitution by constituting a music control signal generation part in a music synthesizer of a common operation circuit means and its control circuit means and executing the operation required for generation of a music control signal in the operation circuit means. CONSTITUTION: A music control signal generation circuit means is provided with a common operation circuit means 308 and control circuit means 301 to 305 and 307 for the control of this circuit means 308, and the operation required for the generation of a music control signal is executed in the common operation circuit means 308. That is, the operation circuit means 308 fundamentally executes one processing at a time under the control of control circuit means 301 to 305 and 207. Thus, the hardware constitution is miniaturized in comparison of a conventional architecture with individual memories and individual private operation circuits. |
