When a knob is at a center position, transmission levels of first volumes of signals input to a first effector (32c) and of second volumes of signals input to a second effector (32e) are both zero: first effector (32a) and second effector (32b) operate independently. When the knob is displaced to right side from the center position, the transmission level of the second volumes (32e) is controlled according to the displacement amount, but the transmission level of the first volumes (32c) stays at zero: the second effector (32b) is connected in series to the first effector (32a). When the knob is displaced to left side from the center position, the transmission level of the first volumes (32c) is controlled according to the displacement amount, but the transmission level of the second volumes (32e) stays at zero: the first effector (32a) is connected in series to the second effector (32b). |
