it is possible to make and add your ow gobo icons however it is extremely complicated and requires high quality pics of the gobo's and a photoshop software. So I would just use one that is closest to the one you need. And I'm not sure about a microlex translator I'll have to get back to you on that. The software I believe can only be used with one USB device at a time. so I'll get back to ya about the rest you were wondering.
Sincerely,
