Waveform data are stored in advance together with reference position information indicative of reference positions, in the waveform data, corresponding to reference timing, such as beat timing, and correction position information indicative of correction positions in the waveform data that are different from the reference positions. The reference timing is advanced when the waveform data are reproduced. In response to arrival of the reference timing, a deviation between a reproduction position of the currently reproduced waveform data and the reference position is evaluated. When the reproduction position arrives at the correction position, the reproduction position is corrected according to the evaluated deviation. Namely, whereas measurement of the deviation, relative to the reference timing, of the currently reproduced waveform data is performed on the basis of the reference position, correction of the current reproduction position of the waveform data for compensating for the measured deviation is performed at the correction position. |
