I have been trying to solve an issue in the Vixen forum regarding my lights not being in sync with the sequence. Initially I though it may have been a software issue or the processing speed of my computer. Some helpful advice from i13, suggested that I may have some better luck if I changed my method of connection. At the moment I have an Open USB Dongle from AAH and while there are no issues with the connection, the lights are not as tight with the sequence as I was hoping. Am thinking that my old computer is not a good match for it. Can anyone advise if I would likely see more reliable results from a DMX Pro dongle or and E1.31 to DMX bridge? Any advice would be appreciated.
