Hi, I have a brand new FLX desk which is a thing of beauty. All the fixtures are patched and working with the exception of three rather ancient Pulsar Chroma Bars. Although they are in the library as a six channel fixture I simply can't get them to work. I've also tried patching them in as a generic LED fixture but to no avail. All I need is individual control of RGB across the three units. These Chroma Bars have 12 DMX dipswitches. The solution, I suspect, will be simple!!! Cheers.
