PURPOSE:To obtain a sound which is close to an actual instrument sound and a sound of depth by multiplexing waveforms of >=2 touches of different strength at a specific ratio. CONSTITUTION:According to a key number, weak stroke waveform process data are read out of the weak stroke data storage part 21a of a waveform memory 21 and multiplied by an interpolation envelope to generate an envelope- added weak stroke signal. Similarly, strong-stroke waveform process data are read out of the strong stroke data storage part 21b of the waveform memory 21 according to the key number and multiplied by the interpolation envelope to generate an envelope-added strong stroke signal. Further, the envelope-added strong stroke signal is multiplied by a coefficient corresponding to a key touch. Further, stroke waveform extraction data are read out of the stroke data storage part 21c of the waveform memory 21 according to the key number and multiplied by an envelope waveform to generate an envelope-added stroke signal. Thus, a musical waveform signal generated by mixing various harmonic components and stroke components at a specific ratio is outputted to a D/A converter 29. |
