If I'm not wrong it's RGB+Amber. I suppose the "amber" is there because RGB cannot produce Amber. So a software cannot automatically feed the amber channel. But you can already handle that one from MadMapper, but you have to choose what you want to send in the amber channel:
- Create a RGB fixture with a channel offset of "1", it will let the amber channel empty
- Create a L fixture with a channel offset of "3", it will feed only the amber channel
For the patching: if you have a 6x6 RGBA fixture patched on channel 1,
- patch the RGB 6x6 (with channel offset=1) on channel 1
- patch the L 6x6 (with channel offset=3) on channel 4
Then you can feed the amber channel with a visual in the UVs and the RGB with something else. If you don't have any use of the amber, just patch a RGB fixture with a channel offset=1 and you can control it like a RGB fixture. The amber should keep on zero.
