Abstract
A musical sound system is operated according to a selected set of a system program and a control program, which are separate from each other and which are related consistently to each other. The system is comprised of a sound unit and a control unit. The sound unit is operable based on a selected system program for producing a musical sound. The sound unit has a floppy disk driver for loading into the sound unit the selected system program and for concurrently loading a control program corresponding to the selected system program, and has a communication interface for transmitting the loaded control program. The control unit receives the transmitted control program for controlling the sound unit according to the control program to thereby hold consistency between operations of the sound unit and the control unit.
