instead of having dead channels in the middle of your mega tree channel line up, wouldn't it be better to put all the channels at the beginning? start at 497 instead of 321. that way when your sequencing, it is a continuous 8640 channels, no space in between. also, if you want to add another rgb display element, you would have 176 channels between dmx, and your mega tree. possibly a 58 node tree topper? i have 1600 nodes, 32 strings of 50 nodes. with 4800 channels, i started at 5793 of universe 2 and spanned 2400 channels into universe 3. that way i have a continuous flow in my channels.
