MIDI 2 X LOOP allows to add two additional effects’ loops to the guitar system. M2L is a loops’ switcher controlled by MIDI interface (by Program Change or Control Change commands) or manually, by using the buttons on the top of the device. Using the MIDI commands it is also possible to mute the signal (e.g. for silent tuning). M2L can be controlled by every MIDI controller and it is particularly recommended as an extension of the G LAB guitar system controllers GSC. Due to its passive signal path it is also possible to use the M2L as an A/B/Y switcher.
