After some help from Paggzy I was able to use External Controller 16 as a pseudo Control Switch in the Axe FX III to use in the controller section of the the pitch block (advanced whammy) so that I could just step on the footswitch on the MMGT10 and do a pitch dive. Paggzy pointed out that External Controllers 1 - 4 are for expression pedals so I get why they wouldn’t work but none of the other external controllers work the way ext ctrl 16 works. I tested 5 through 15 and none of them will do what 16 does. Is this something on the fractal side of things? What is the significant difference between external controller 15 and external controller 16?
