I have been using Sunlite SUIDI USB-DMX interfacesfor the past 4 years and have about 40 installations running including 7 musical fountains. The way to go is Windows XP. Almost every interface has some problem with Vista.

We have stocked up on boxed XP copies ( around 30) so that we can go thru another year of projects. But it's scary. Sunlite says they will be out with all the neccasary developer tools for Vista to support SUIDI interfaces within a couple of months. Hope for the best
