Abstract:
An effect adding apparatus comprising:effect assigning means for assigning a plurality of effects to a corresponding input plurality of musical note waveforms received externally at a wave sampling period;time division control means for dividing the plurality of musical note waveforms into a plurality of groups of musical note waveforms for the corresponding plurality of effects and for outputting the groups of musical note waveforms on a time-divisional basis;assignment changing means for determining whether the sum of operation times required for adding the assigned plurality of effects to said plurality of groups of musical note waveforms has exceeded a waveform sampling period, and for changing types of the plurality of effects to be added by said effect assigning means when said changing means determines that the sum of the required operation times has exceeded the waveform sampling period;effect adding means for receiving the plurality of groups of musical note waveforms on a time divisional basis from said time division control means, and for adding the plurality of effects to the plurality of groups of musical note waveforms; andoutput means for accumulating the musical note waveforms to which said effect adding means has added the plurality of effects at the waveform sampling period, and for outputting a resulting musical note waveform.
