Audio system for reproducing plural parts of music in perfect ensemble

摘要

An ensemble controller (110) records a performance on a MIDI musical instrument (174) in a data field (md) of a MIDI file (mf) synchronously with playback of a piece of music stored in a compact disc player (120), and the data read-out speed is stored in the control data field (mc) of the MIDI file (mf) together with an audio identification code (AID) assigned to the piece of music reproduced; when the performance is reproduced synchronously with the playback of the piece of music, the ensemble controller (110) adjusts a clock signal (CL1) to a frequency corresponding to the data read-out speed; while the ensemble controller (110) is making the composite apparatus (100) reproduce the ensemble, the magnetic disc driver (130a) clocks the time intervals between the data transmission of event codes by using the clock signal of the same frequency; this results in the perfect ensemble.
