I've got a real simple question that I can't seem to find a straight non-conflicting answer to anywhere: Assuming power isn't a concern (external supply) how many LEDs can be addressed by the Core XT and the Commander Pro, both total and per channel? I've got a bunch of 144/1m strips I want to use for a very low brightness but high resolution effect and while powering them isn't an issue addressing them is. I haven't found anything that can address more than ~96 LEDs total yet, and while I could just wire something up to an Arduino I'd rather avoid any more soldering than I've already done.
