Midi Maestro and Pigtronix Infinity mapping

Getting to grips with the MM app though it’s somewhat trial and error. Have a custom mode that has all the buttons where I prefer them.

Anyone else having any success controlling their Pigtronix Infinity? I’ve set mine to channel 3, but CC 3/24/0 or 3/24/1 or3/24/127 doesn’t start a loop as the mapping seems to suggest. I’m obviously doing something wrong or missing something.
