Abstract
A selector is provided for selecting a predetermined effect. Instruction as to whether this effect should be imparted or not is not made instantly in response to an output of this selector but made in association with instruction of start of tone generation by a key-on event signal. For example, even when a state in which an effect is selected is brought about in the course of generation of a tone without selecting an effect, this effect is not imparted to the tone which is currently being generated. Upon instruction of generation of another new tone in this state, instruction of imparting of the effect is made for the new tone so that the effect is imparted to the new tone from the start of generation of the tone. Conversely, when a state in which no effect is selected is brought about in the course of generation of a tone which is imparted with an effect, the effect is kept imparted to the tone which is currently being generated until generation of the tone is ended.
