ABSTRACT:
A tone signal generator includes a plurality of tone generation channels, and a tone generation control data memory for storing instruction data for instructing tone generation or tone release and execution data for instructing execution thereof, for each tone generation channel. The tone signal generator also includes an execution device for executing the tone generation. The execution device executes the tone generation or the tone release for each tone generation channel at an assigned timing in the sampling cycle to the tone generation channel when the instruction data is written in the tone generation control data memory corresponding to the tone generation channel, and then the execution data is written in the memory corresponding to any tone generation channel. After the writing of the instruction data, the executing data is written into the memory. This executing data triggers the tone generation of channels where the instruction data has already been written. As a result, the tone generation in multi-channels is performed at the same time.
