Sorry, Bome MIDI Translator Pro does not natively recognize game pad input. As you mentioned, I developed MIDIBuddy that does have some game controller support to convert to MIDI so theoretically if your DMX controller could handle MIDI you could do:
Game Controller → Bome MIDI Translator Pro → DMX lighting application.
MIDIBuddy is a Windows only solution.
