Abstract
A user records a part of a piece of music performed on the composite audio system into and reproduces the performance from a floppy disc in ensemble with another part of the piece of music; while a compact disc player is producing an audio signal from audio data codes, the composite audio system produces event codes representative of local peaks in the audio signal for timing control, and stores these event codes together with event codes representative of note events and duration data codes in the floppy disc; while the composite audio system and compact disc player are reproducing the parts of the piece of music, the time intervals among the tones are prolonged and shrunk by using the event codes for timing control and actual local peaks so that the tones in one of the parts are produced synchronously with the tones of the other part.
