Note that in 16 and 30 channel mode, each "fixture" (group of 3 LEDs) has its own master dimmer that needs to be set to max brightness if you want to use it with an RGB matrix (a single light has 12 "fixtures" in 30ch mode). I had to map a single slider to all of these parameters at once and set it to max in order for to get the matrix to work.
