VERY late for a reply to this, but I just noticed your post... Try automating the free DMX application called Freestyler (http://users.telenet.be/freestylerdmx/) using autoit. It's buggy as hell, but provides a simple GUI to control multiple DMX fixtures using a windows machine and any of a dozen different cheap USB DMX adapters, yours included (I think.) Don't bother rolling your own if you can make this program "dance" for you. Of course you can also program chases and complex sequences of actions using the program itself... but if you're doing something in response to an *input*, perhaps you're better off using autoit to drive the DMX adapter directly.... or a combo of the two. Have fun, (er hope you *had* fun 2 years ago. Eric.
