Melody information representing pitches and durations of tones is stored in a first area of a RAM whose addresses are designated by a first address counter of an address register. Performance information representing tone colors, vibrato, etc. is stored in a second area of the RAM whose addresses are designated by a second address counter of the address register, while the stored melody information is read out and reproduced. The melody information and performance information stored in the respective areas of the RAM are read out in associated relation with respect to one another, to be sounded from loudspeakers.
