I've noticed this before, and I think you may or may not have addressed the issue, I tried looking back but couldn't find anything. But on the fixture profiles for many of the led fixtures that have an extra 3 channels on the end for dimmer/strobe the rgb mixer will never work for these. It WILL work, but it will only light up one "pixel" or section of the led fixture. So the 2 thats my concern right now are the adj mega bar/colorpalette when trying to use the rgb mixer for the 27 channel mode on chauvet and 11 channel on the mega bar, it will only light up section of the light. Hope this is making sense, also the fx generator will work, however only again lighting one section of the light, but again I think i read the efx generator wont work with fixtures with the extra channels for led fixtures. But id like to address the rgb mixer issue. Thanks!
