I purchased another MIDI cable today (per your suggestion) in the attempt to facilitate the tuner displaying on my MC6 MKII. The tuner is triggered on my AxeFX III when I press the assigned button, but still will not display on my MC6. This is with the suggested new firmware 3.1.0 and the new 1.9 on the AxeFX III. I can not seem to setup the looper properly either, even though I've assigned the CC #s on the AxeFX III, and have the same numbers for each switch. The looper doesn't even come up on the AxeFX III's screen. Help!!
