Good news, my mega tree is working perfectly thanks to your help, Ebuechner, Phrog30, and Jimmy. The problem was that the start Chanel does not match between the controller and x-lights, in the controller I change the universe # of 1,2,3,4,5, etc. To 13, 14, 15, 16 etc.(BINGO) Thanks to each one of you, I am learning more and more. Have a nice week, Jimmy
