Abstract
Abstract Audio data of a predetermined piece of music is recorded on a compact disc. A sequence of musical tone data is stored in an auto-play memory. Also stored in this auto-play memory are a time control command, an access command and a play command. An instrument controller reads out these commands to surely control the auto-playing and reproduction of data from the compact disc in synchronism.
