Combining three pedals into one convenient and clutter-free unit, the RPU-3 offers a real grand piano pedaling experience. With separate 1/4″ outputs for each of its three pedals, the RPU-3 is compatible with keyboards such as Roland?s FP-90, FP-60, and RD-2000 pianos. In addition to providing the same pedal configuration as a grand piano, the RPU-3 also provides hands-free control of various instrument functions, such as selecting registrations or activating vocal effects on the FP-90.
