摘要： 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.

摘要： In a MIDI signal processor, note on messages and note off messages are extracted from an input MIDI signal. A device detects that a first extracted note on message of a channel number and a note number is followed by a second extracted note on message of the same channel number and same note number without being followed by an extracted note off message of the same channel number and the same note number. The first note on message is outputted but output of the second note on message is inhibited when the detecting device detects that the first note on message is followed by the second note on message without being followed by the note off message.
