Abstract
When a plurality of different effects are added to a plurality of musical notes at the same time, the plurality of musical notes are divided into a plurality of groups for musical notes, and the groups of musical note waveforms are delivered on a time divisional basis to an effect adding circuit, which adds the respective effects to the groups of musical note waveforms, accumulates at each waveform sampling period the musical note waveforms to which the respective effects have been added, and outputs a resulting musical note waveform. The sum of operation times required for adding the respective effects to the plurality of groups of musical note waveforms can exceed a sampling period depending on types of effect to be assigned. To avoid this situation, it is determined in advance whether the sum of the operation times required for adding the effects exceeds the sampling period. If so, addition of an effect to a musical note waveform where a depth of the effect is minimum is stopped.
