Abstract:
    A music player/recorder includes two data sources, a controlling system and two sound source or a recording system; one of the two data sources supplies event codes representative of first tones and delta-time codes representative of time intervals between the events as defined in the MIDI standards to the controlling system, and the other data source supplies audio data codes representative of second tones and time codes representative of a lapse of time to the controlling system; the controlling system counts tempo clocks, and converts the number of tempo clocks to a reference lapse of time to see whether or not the difference between the lapse of time and the reference lapse of time is ignoreable; when the answer is given negative, the controlling system varies the time interval so that the first tone is produced synchronously with the corresponding second tone.
