You keep mentioning Helix as if the rest of us should just know what that means. If Line 6 Helix, that's a whole family of effects and controllers. If something else... In any case, please let us know what unit you are using.

What app are you using to pass MIDI commands. Is it BIAB? Is it a 3rd party app?

There are a few apps for assigning commands in the macOS. I'm pretty certain that SteerMouse will not do what you need but there are others.
