I have the Axe FX ii mark ii and I'm stumped on how to set up the looper. I have a midi foot controller and I see that the midi numbers for the looper record/play functions are #28,29. But when I hit those numbers on my foot switch, the looper doesn't activate, the patch just changes. I know I'm missing something big here but I haven't been able to find any answers. Help would be very much appreciated.
