Audio system for reproducing plural parts of music in perfect ensemble
First Claim
1. An audio system for reproducing a piece of music in ensemble with another piece of music, comprising:
- a first data source having a first memory space for storing a set of first music data codes representative of said piece of music, and responsive to a control signal representative of a data transmission rate for transferring said first music data codes from said first memory space;
a second data source having a second memory space for storing a set of second music data codes representative of said another piece of music and different in format from said set of first music data codes, and responsive to said control signal for transferring said second music data codes from said second memory space;
a data-to-sound converter for producing a first sort of sound and a second sort of sound on the basis of said first music data codes and said second music data codes, respectively; and
an ensemble controller connected to said first data source, said second data source and said data-to-sound converter, having a data processing capability, and supplying said control signal to said first data source and said second data source through a data processing for equalizing a first data transmission rate for said set of first music data codes with a second data transmission rate for said set of second music data codes.

Abstract
An ensemble controller records a performance on a MIDI musical instrument in a data field of a MIDI file synchronously with playback of a piece of music stored in a compact disc player, and the data read-out speed is stored in the control data field of the MIDI file together with an audio identification code assigned to the piece of music reproduced; when the performance is reproduced synchronously with the playback of the compact disc player, the ensemble controller adjusts a clock signal to a frequency corresponding to the data read-out speed; while the ensemble controller is making the composite apparatus reproduce the ensemble, the magnetic disc driver 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.
