Abstract
A musical-tone signal controlling apparatus includes a processor which executes a musical-tone controlling process on an input musical-tone signal supplied to the processor, the processor including a delay unit which executes a delay process on the input musical-tone signal; a first discriminator which determines whether or not the input musical-tone signal to be supplied to the processor has become null; a second discriminator which determines whether or not the output musical-tone signal processed by the processor has become null; and a reset circuit which automatically resets the delay unit when the second discriminator determines that the musical-tone signal processed by the processor has become null after the first discriminator determines that the input musical-tone signal to be supplied to the processor has become null.
