Did it ever work for the Express on an older version software? The reason I asked was I always heard the original "shimmer" effect was a effect generated by the hardware of the LOR controller and the software only called for that effect to turn on. Both LOR and the older LSP could call up that hardware effect. Now I had some RGB floods that when that effect was called up would blink at a much slower rate and I didn't know if it was 1. a limitation of the flood itself, 2. a limit of dmx, or 3. just because the flood was not using the LOR controller therefore the hardware call wasn't there.
