TECHNIQUE FOR REPRODUCING WAVEFORM BY SWITCHING BETWEEN PLURALITY OF SETS OF WAVEFORM DATA

摘要

The object of the present invention is to switch between a plurality of sets of waveform data at desired timing while preventing occurrence of noise. In response to an instruction for switching from a currently reproduced set of waveform data (20) to another set of waveform data (20'), either a switching position in the other set of waveform data (20') or a switching in the currently reproduced waveform data (20) is set as end timing for ending the reproduction of the currently reproduced set of waveform data (20), with reference to switching position information (25) of the two sets of waveform data. If the switching position in the currently reproduced set of waveform data (20) is present within a 50 msec time range before a switching position in the other set of waveform data (20') that is present immediately after the switching instruction, the switching position in the currently reproduced set of waveform data (20) is set as the ending; if not, the switching position in the other set of waveform data (20') is set as the end timing.
