The RPU-3 pedal unit offers the three pedals of a grand piano in a convenient, space-saving package. With 1/4-inch (standard jack) cables for each pedal, the RPU-3 is compatible with keyboards such as the new Roland FP-60x and FP-90X models and the RD series pianos, including the RD-2000. The RPU-3’s pedals, arranged just like those on a grand piano, can also be used to control various instrument functions, such as the Looper and harmony effects on the FP-90x.
