That's a good workaround for now, thank you!
Just a heads up, even with the Scenes in a "Solo Frame" widget in QLC+, it looks like there's some limitations - for example, if I have a "Red" function, and a "Blue" function, in Sound Show, I can successfully switch between Red and Blue. However, if I press "Red" to turn on the Red, I can't press "Red" again to toggle it off. I need to set up a separate function called "Red Off" in order to do that. This might get fixed in the new update you're working on, but just wanted to make a note of it.
Thanks again for the quick responses!
