Actually, you dont need all these channels, because we need only 3 colors to make "all of them", since a fourth channel to turn off is usually global and we can do it using only one wifi channel for all pixels to turn off at the same time.
But im fine if you can do it using scrips. Idk how they work, only its about LUA, console, and editable with PROP tool.
Have you seen my screen? it uses all but 9 wifi and portal channels (197 out of 200 and it still only is 8x8) and would use more but 3 extra pixels couldn't fit in anywhere, and INST/ARAY won't fit either :D
