so now it should be ok, i am sorry i sent you the wrong file previously, so for pixbar 600 you will get the uv chanel on the first custom fader.
For the sun.x my problem was that i get only 2 custom fader so i used them for auto mode and speed, in this new file you will get the dimmer curve on the zoom fader.
To merge 2 files, you need to open the files with text editor and copy past from one to the other one the manufacturer you need to move copying from
<manufacturer label="XXXXX">
to
</manufacturer>
