PURPOSE:To decrease the constitution scale of hardware by enabling complicate timbre variation by simple constitution. CONSTITUTION:The electronic musical instrument is equipped with a musical sound waveform generating means 10 which generates plural musical sound waveform signals according to performance information, a filter coefficient generating means 14 which generates plural filter coefficients, a waveform composing means 11 which composes a composite waveform signal of plural musical sound waveform signals at an optional ratio and outputs the composite waveform signal, a filter coefficient composing means 15 which composes a composite filter coefficient of plural filter coefficients at an optional ratio and outputs the composite filter coefficient, and a filter means 13 which filters the composite waveform signal. |
