PROBLEM TO BE SOLVED: To synchronize the period of a signal for controlling musical sound and the periods of the tone, the beat and the bar of music that is automatically performed in accordance with a synchronous clock such as a tempo clock. SOLUTION: A signal generation means changing a synchronous clock signal by a prescribed value at the time of receiving it, initializing it when it reaches a prescribed value and generating a first signal which is periodically changed, a target value acquirement means generating a second signal based on the first signal generated by the signal generation means at every first prescribed time, generating a third signal operated on the second signal and acquiring the target value of a fourth signal by operating the third signal on the second signal, an interpolation means interpolating the value of the fourth signal toward the target value of the fourth signal, which is obtained by the target value acquirement means, at every second prescribed time shorter than first prescribed time and a musical sound control means controlling musical sound based on the value of the fourth signal interpolated by the interpolation means are installed.
