This is kind of a strange one to me. I have a 32 string Megatree. Each half of the tree is driven by an active hub. If I am in test mode and go to RGB, select background and turn what should be red to 255 half of my tree is red, the other half is blue. If I turn all green, half green and the other half red, All blue half blue and other half green. In other words Half works as expected, the other half is 1 color off. Tested in LSP hardware test and everything seems to work ok. I have not run a sequence yet so I do not know how it will react, but I repost after a show.
