This isn't a technical support question but there doesn't currently seem to be anywhere to post what people are doing with their pedals so I thought I'd throw these in here, I'm using the MC6 to control some Strymon pedals. This opens up a few possibilities that you don't get on the pedal easily (especially in a loop controller environment.
First shot - MC6 bank to control on / off of Strymon pedals
Second shot - Timeline looper control including repeats and delay time through the expression pedals.
Third shot - timeline control of specific faves. MC6 is enormously capable and I've not even scratched the surface
