You wanna go to the “Matrix” and click on blank area for “Source”. Select which Macro you want to use. Then click on the blank area for “Destination”, select which effect you’re wanting to use. In this example, i’ve selected Macro 1 to control the Chorus Dry/Wet Mix. Then I adjusted the amount to be all the way to the right (100% wet). Now, in the Mod Remap area (LFO looking thing), re-shape it from the default linear ramp up to having the first 50% to be all of the way down, and the last 50% to be all of the way up. This results in having the dial anywhere to the left to have 0% chorus, and anywhere to the right to have 100% chorus.
I hope this helps, and I hope I wasn’t too confusing lol
