Came here to find out about RGB Fusion alternatives. Their software is absolute thrash. There is no manual control for addressable RGB lights. It doesn't even ask you how many LEDs you have per strip. It just sends out the generic shift register style rainbow commands. You cannot have a static display of, say, half red and half white LEDS. It doesn't know how to do that, cuz it doesn't know how many LEDs you even have!
For my (very expensive) X570 Aorus Master motherboard, both the aRGB headers send out the same signal... WHY HAVE 2 HEADERS THEN!!! Someone please make an alternative software. Long story, but I need to use this motherboard for my build. I can't switch to Asus.
