so here is what you do. in the dmx universe grid insert 3 of the _generic RGb profile to get your 9 channels of RGb control then use one of the profile I have just linked you too for your channel 10 11 and 12 control modes and master dimmer. Let me know if this make sense. I sincerely apologize about the delay.
