ok, so i finnaly found the problem, as i'am not the one who made the first file for you, i did not noticed this before!
the fixture you are requesting use subfixtures and cuety do not manage subfixtures, so this is why you weren't able to see the fixture you requested in cuety.
Now to let you use your fixture anyway, i created a special cuety patch.
SO you first ned to patch the special cuety 11ch mode, and then patch 3 generic rgb par. This way you will be able to control your complete fixture.
But remember that to acces the 3 pixels of the bar you need to set the main dimmer between 41 and 80.
I hoppe this time it will be ok,
