Midi control of Red, Green and Blue channels

[Blaize110]

Hi,

I might be completely blind here, but I can find the optoin in the list of midi assignments for the Cyan, Magenta and Yellow channels of a fixure, but cant find any for Red, Green and Blue. There may be a perfectly good reason for this but I was wondering if anyone can enlighten me as to why or if there is a way to assign midi channels to th RGB parameters?

Thanks in advance
Rory

You can use the cmy for control

[Mattotone]

CMY = RGB

Cmy = inverted rgb

[LJ_krede.dk]

CMY = RGB

Cmy = inverted rgb

DMX * C = DMX * R
DMX * M = DMX * G
DMX * Y = DMX * B

BUT (always a but)

If you selected a fixture with RGB and a fixture with CMY the values are inverted. really weird

if you selected the RGB first and then the CMY fixture
DMX * C = (255-DMX) * R
DMX * M = (255-DMX) * G
DMX * Y = (255-DMX) * B

and vice versa if you selected the RGB fixture last

(I know it is not mathematically correct but you get the picture)

I really dont know why

Thanks for the help. I was pretty sure something like that couldn't not exist. Just a matter of finding it.
