A first keyboard receives a first sustain signal upon activation of the first switch and sustains a first note upon receipt of the first sustain signal. A second keyboard receives a second sustain signal upon activation of the second switch and sustains a second note upon receipt of the second sustain signal. The keyboards are independent from one another such that the first keyboard does not send a signal to the second keyboard to control the second keyboard, and such that the second keyboard does not send a signal to the first keyboard to control the first keyboard.
