I setup several Single Stand models for my AC lights that I still have. Some are strands are Green, some strands are Red, some are Blue and some are White. So I created the Single Strand Model with the "Single Color Green"
I noticed in the Sequencer that when I used "On Effect" on a strand that was Green, it added the effect on the grid as Red. In LOR, it's smart enough to know its a Green strand and plots the effect as Green.
Now, when I previewed my song in House Preview, the "On Effect" on the green strand didn't show up at all. The green strand never turned on. I found out that I had to change the color to green in order to see the green strand show up as green.
Seems like there is a bug here. When selecting "Single Color Green" in Single Strand Model setup it. It should plot the on effect as green and it should show up in House Preview without me having to change it to green.
