The MPX R1 MIDI Remote Controller performs as a dedicated MIDI controller for the Lexicon MPX G2, the MPX 1, or as a stand-alone MIDI control unit. Any way you use it, you’ll appreciate its rugged, road-worthy construction and straightforward control surface. The MPX R1 has two basic operating modes: Program Mode and FX Mode. Program Mode is used for sending MIDI Program Change messages. FX Mode is used to send other MIDI data such as Controller messages, and for selecting the unit’s built-in 4-state relay. When used with the MPX G2 or MPX 1, FX Mode functions like a “virtual pedalboard”. Individual effect blocks can be turned on and off, and three-state LEDs (off, red and green) indicate whether the effect block is unavailable (not programmed as part of the preset), off or on. The front panel FX button toggles between Program and FX modes.
