Question I am controlling the G-Major 2 from a MIDI board. I 'd like to connect an expression pedal on this board to control some parameters of the G-Major 2. What kind of pedal should I select    Answer In this case you should contact the manufacturer of the MIDI board as they must have some specific recommendations for pedals. when connecting to the MIDI board, the pedal will then send a MIDI CC to the G-Major 2 and no calibration is required in the G-Major 2.  For best results,  the pedal should be linear. You will be able to adjust the curve on the G-major 2 whether you are assigning it to effect parameters or to global volume.
