I have vixen and its working properly. I was thinking maybe there was an issue with the dmx firmware on the usb dongle and the lsp v2.5. If I create a sequence on vixen, it works perfectly. Now with the same set up, I make a similar sequence with lsp (basic version), set up the controller as usb pro, start channel at 1, and test the hardware, I get nothing. If i try running the sequence with the output button enabled, nothing. Ive posted in the lsp forums and the lsp software forum on this site, but havent figured it out yet...
