Okay, this is a weird request for an interface for the Helix.
I'm a traditional pedalboard guy who liked to tweak settings on the fly with the edge of my shoe on various pedal knobs (usually with EQ, delay and reverb settings) and I'm looking for a way to do that on the fly with my hands. I have a bad back and can't bend down much and I'm thinking of using this primarily during rehearsals to tweak a patch but also use it live (need a little more mix and less feedback on my delay, so I'll play a chord, and quickly tweak it by hand.) I could do this with snapshots, with my bare feet to use the touch-sensitive switches, use an expression pedal, but I'm looking to potentially change any one or two of several parameters on multiple effects as needed.
I could hook up a Win 10 tablet or laptop to do just that and run HX Edit, but I'm also curious is there is a way to assign knobs on a physical MIDI controller that I can connect directly to the Helix via MIDI or USB.
Something like this would be amazing: https://www.sweetwater.com/store/detail/MPKmini2BB--akai-professional-mpk-mini-mkii-keyboard-controller-limited-edition-black-on-black
Any thoughts? It's a crazy request, but anyone willing to think of a possible solution?
