Abstract
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.
