The RPU-3 combines three pedals into one convenient and clean unit, offering a true piano pedal experience. It features separate 1/4" outputs for each of its three pedals, making it compatible with keyboards such as the new Roland FP-7F and RD-700. In addition to providing the same pedal layout as a piano, the RPU-3 also offers hands-free control of various instrument functions, such as the Looper and harmony effects of the FP-7F.
