Abstract
Abstract In a MIDI Signal processor, MIDI data is reproduced from a recording medium. The reproduced MIDI data is outputted. An interruption of the reproducing of the MIDI data is detected. A MIDI status byte is detected after the interruption ends. The outputting of the reproduced MIDI data is suspended when the interruption is detected. The suspending is continued until the MIDI status byte is detected.
