Essentially:
- please file requests at the personality site:
http://www.avolitesdownload.com/Persona ... efault.asp
- if a fixture is already available as .d4 (for Titan, Diamond4), just get this personality, open it in PersonalityBuilder, and export R20-files.
- this will generate two files: .R20, and .VIS. Copy the .R20 to c:\program files\Avolites\Visualiser\Personalities, and the .VIS to c:\program files\Avolites\Visualiser\Extensions
- now you can start: patch this fixture, and try controlling it in Visualiser
- it's quite likely that some things need some tweaking in the .Vis file. As a starter, quite often the strobe channel has wrong values, and the fixture remains dark. Either get the Visualiser documentation, and/or view some other .vis files, to see which values might work
That's not too complicated, and there is a good chance you'll be controlling your virtual fixtures after a short while.
