A while ago I was testing out a Marquee console and a Whole Hog II side-by-side – back when I had WYG R20 at a University I was teaching. I had this great device called a WYG-It 2, which was two DMX universes, a midi port, and connected to my computer/WYG setup via USB.
Check out the WYG-It 2:
The WYG-It 2 allows you to output DMX directly into WYSIWYG from a console. It’s a few bucks shy of $1200, and if you’re doing a lot of preprogramming or Pre-Viz in WYG, you need it. I wish I had one now! The unit doesn’t need external power, and I never had one freeze up, ever.
