Ok what I was really meaning was what exactly is in your Brain, ie is it just a single input switching a single output and if so what input?
You could do it this way, I will just use input 1 as an example but you would obviously need to change to suit, also I have used UserLED 1111, if you already use that then again you would need to change to suit.
What you would do is in the Brain have it look at the input and also look at the user LED, you would then Or them. Your macro would then turn the UserLED on. See screenshots.
Just a word of caution, using macros under 100 is not the best idea as they are reserved for Machs internal functions, at this time M17 is not used for anything but in the future it may well be so best to use m117 or something similar.
