Abstract
Among the stored musical waveform in a data format, a waveform segment to be repetitively read out as a loop is designated by a user of the instrument. Upon designation of the waveform segment having a loop length LL anew, a loop time length TL is computed corresponding to the loop length LL, and the number of measures MN is determined corresponding to the loop time length TL (steps S11 and S12). Thus determined loop segment in the measure number MN is temporarily subdivided according to a sixteen-beat rhythm rate (steps S13 and S14), zero-cross points near the temporary subdivision points are then searched for, and the located zero-cross points are determined to be definitive division points (step 15). Each of the divided sub-segments are subject to time axis scaling at each scale factor such that the segment should be superimposed onto another intended musical phrase in a matched rhythm and tempo.
