these type of things are never simple.

and specs always change.

the catalyst presets are in a semi-coded form - to stop people from editing them manually - because they may or may not reflect any external protocol. They are not designed to be edited or translated.

The best way to communicate with a lighting console - would be using a language it implicitly has to understand - like DMX.
