PROBLEM TO BE SOLVED: To make possible obtaining a new performance effect and to make a musical effect rich by reproducing while switching a pitch of a waveform while reproducing to the pitch answering to after performance information from its input point of time when the after performance information is inputted while reproducing the waveform read out from a waveform memory. SOLUTION: An A/D converter 4 A/D converts an inputted analog waveform signal to a digital waveform signal, and a digital signal processor(DSP) 8 digital reproduction processes the waveform data to store them in a waveform memory 12, and a D/A converter 14 converts the digital waveform signal reproduction outputted from the DSP 8 to output it. A CPU 22 controls the DSP 8, and when the after performance information is inputted from a key board 30, and a reproduction start is instructed while reading out the waveform data, it ends the read-out of the waveform data by former performance information until then, and reads out the part after the timing when the after performance information among these waveform data are inputted by the pitch answering to the after performance information. |
