I added a new group and when I drag in a new fixture it creates 4 copies of the same fixture with the same DMX address. If I try to delete the extras, it deletes all 4 copies.
I actually answered my own question. It turns out that there are 3 groups of LED’s in the wash/zoom lights I am adding and that allows SS to control each group of LED’s in the fixture separately so it makes perfect sense and works awesome!
