I have 23 4-color LED Mini Trees and 12 4-color LED Twig Trees in my display. What is the easiest way to set them up in the 'layout' tab so that I can control each tree by it's individual colors. I have tried setting them up as a tree, with 4 strings which gives me 4 channels, but when I try to set up a group by color I am not able to. Only way I can get to the individual strings is on the sequencer tab. Do I have to create a model for each tree by color, and stack them on top of each other? Is there an easier way?
