When generation of a musical tone is instructed, the LEDs of the indicators which are associated with tone parts of the musical tone and whose quantity corresponds to volume information of the musical tone, are lit. When a count value of the counter section reaches zero, one of the LEDs is turned off or on, and the lighting time information in the register section is reset in the counter section to re-start a countdown operation.
