I have literally just started with XLights. I used LOR last year to control a single AC controller, and that's it. I've added in pixel lights this year and am annoyed at how the programming works for them in LOR. I've moved my AC controller to be #1 so it mirrors your setup. So now when I enter in my start channel field, how should it be formatted?
Also, 3 wasn't the first line, I had to scroll down in the screen shot.
