PURPOSE:To improve the technique of playing by detecting non-coincidence between a real play interval data and a standard interval data, stopping supplying the real play interval data to a sound source only for a prescribed time, and supplying the standard interval data to the sound source. CONSTITUTION:When a keyboard is pressed, according to the operation, a real play MIDI data (note-on message) PMIDI (ON) is supplied through a MIDI controller CNT 5 to a sound source 7, and sounding P is executed. When the MIDI CNT 5 is on the condition of PNOnot equal to RNO in respect to the supplied real play MIDI data, the CNT 5 writes a channel CH, note number PNO and the note number ROM of a standard MIDI data RMIDI (ON) into a memory 10. After the lapse of prescribed time, a MIDI data PMIDI (OFF) is generated and supplied to the sound source 7, and sounding is forcedly stopped. Afterwards, the standard MIDI data RMIDID(ON) is immediately supplied to the sound source 7, and sounding 2 on correct pitch is executed. |
