In a method of generating musical tones through a plurality of channels according to performance information by means of a processor placed in either of a working state and an idling state and a buffer connected to the processor, control information is successively produced for the plurality of the channels according to the performance information when the same is successively inputted. A regular task of the processor is periodically instituted according to the control information for successively executing a routine synthesis of waveform samples of the musical tones allotted to the plurality of the channels and for temporarily storing the waveform samples in the buffer. It is detected when the processor occasionally stays in the idling state for instituting an irregular task of the processor to execute an advance synthesis of a waveform sample of a musical tone allotted to a particular one of the channels and for reserving the waveform sample in advance. The processor is controlled to skip the routine synthesis of the waveform sample allotted to the particular channel while loading the reserved waveform sample into the buffer. The waveform samples are sequentially read out from the buffer in response to a sampling frequency to generate the musical tones through the plurality of the channels.
