Abstract
Tone data produced by operating a keyboard is stored in a RAM to be saved into a tape recorder through an interface. Of a plurality of music numbers saved in the tape recorder a selected one is loaded into the RAM through the interface. A tone generator converts the tone data from the RAM into a tone signal which is sounded from a loudspeaker. The save and load operations are all controlled by a CPU.
