Any device that has an expression pedal input, such as the Nektar Pacer foot controller, is ideal for the Nektar NX-P Universal Expression Pedal. Because of its polarity switch, the NX-P can be used with almost any piece of equipment that has an expression input. At Sweetwater, we're huge fans of Nektar's music production tools, and the Nektar NX-P expands the lineup with universal expression control.
