ABSTRACT:
A musical performance data reproduction appparatus for reproducing stored performance data compensated with a just-beat function. A clock generator generates a clock proportional to a given tempo. A clock counter counts the clock to output incremental clock data. A clock converter converts the incremental clock data into reproduction clock data with a nonuniform increasing rate. The performance data is then reproduced based on the nonuniform reproduction clock data and a time base of the reproduced performance data is expanded/compressed so that reproduced tones are just-beated with respect to a reference beat time.
