PURPOSE:To smoothly follow up the output of automatic performance at the time of tapping by eliminating a time difference (deviation) in score time, which is generated at the time of the tapping, with a certain function. CONSTITUTION:A tempo clock is supplied from the tempo controller 1 to a sequencer 2 through an MIDI cable. At this time, the quantity of the deviation in score time at the time of the tapping is found and reduced according to the specific function. Then performance data are read out of the performance data memory in the sequencer 2 according to the tempo clock and sent to a sound source 3. Waveform data corresponding to the performance data are read out of the sound source memory of the sound source 3 and outputted to a sound system 4. Then while the score time deviation quantity is reduced according to the specific function, the current score time is updated. Consequently, the output of automatic performance at the time of the tapping can smoothly be followed up. |
