Hello again,
after struggling to see how to get HSL attributes to work, I realised I shouldn't have created individual Dimmer channels for the R, G & B fixture LED groups, but used the RGB type for each "pixel".
I reworked the 53-Ch mode, then decided I might as well do some deleting and create all of the other modes as well, to complete the fixture profile.
See new version attached.
If any of the experienced users out there could take a look and comment on any corrections you think I should make, that'd be wonderful.
(these inexpensive 2x8 battens are the main part of my current setup)
I've added a link to the pdf for convenience.
