Source four with myDmx

As it's a controller made by American DJ, probably best to talk to them, but you should just need a generic dimmer profile which is more than likely in their stock library but I really don't know anything about their software.

If they're conventional Source IVs (i.e. not the Revolution), use the Single Channel or any of the PAR profiles found in the 'generic' Scan Library - one for every dimmer channel in your pack. Profiles are more typically supplied by the controller's manufacturer, if they don't supply the software necessary for users to build their own.
