Hey Dave D, Welcome to Forums
What you’re trying to accomplish should be fairly simple and involves just a couple of commands. So, before going right into it please let us know what size of the loop would be ideal as a start value? (the zero position where your knob starts to engage from)
Here u go
Hi buddy,
You’ll need these 3 lines on the same button! See img!
Loop size on (button, direct and the loop size value you want)
Loop set on (button, hold)
Flux mode (button, hold)
at last, assign the deck (my screenshot has deck D)
Good luck!
