Now the Groove XR can full external controlled by any MIDI/USB keyboard/controller.
Multiple USB controller can be connected and drive independent each of the 12 sounds engines available.
2 players and Combination, Qranger are also Midi controlled.
You can leave the Rack away from you and with one or more USB keyboards you can full control.
Regards
