Abstract
While a normal tone of a designated pitch is being generated in response to key depression or other performance operation on a keyboard or other performance operation device, the tone is controlled in response to manipulation of a pedal or other auxiliary performance operator. Namely, once the auxiliary performance operator is manipulated during generation or sounding of the normal tone, generation of an additional tone related to the normal tone is initiated. In this case, in correspondence with ON/OFF operation of the auxiliary performance operator, a resonant tone is generated, as the additional tone, which is peculiar to the currently-generated normal tone and which is also peculiar to the ON/OFF operation of the auxiliary performance operator. Particularly, if the normal tone is still being generated when the auxiliary performance operator has been returned from the ON state to the OFF state, a returning tone related to the currently-generated normal tone is generated as another additional tone. The returning tone is a vibration-suppressed tone occurring as a mechanical vibration producing the resonant tone is ceased.
