Abstract

PURPOSE: To impose attack pitch control and delay vibrato control at the same time by starting the vibrato control over a musical sound signal a specific time after modulation control by an attack pitch control means ends according to the output of an attack pitch end detecting means. CONSTITUTION: When the attack pitch control is performed, the attack pitch control means 3 finishes the modulation control over the pitch of the musical sound signal generated by a musical sound signal generating means 2 in the beginning of sounding, which is detected by the attack pitch end detecting means. When delay vibrato control is performed, a delay vibrato control means 5 starts a delay time not immediately from the beginning of sounding, but when the end of the modulation control by the attack pitch control means 3 is detected. Then the vibrato control over the musical sound signal is started the specific delay time later. Consequently, the effects of both the attack pitch control and delay vibrato control can be given to the same sound securely distinctively.
