I have a 15 minute fade programmed in a show. In the middle of that fade, somebody turns on a light. That part is easy - I set up the areas to bump up with the action. My question is: at another point while the long fade is running, somebody turns off that light on stage. How do I set it up so the lights affected by the light being turned on onstage rejoin the fade at the level they would be if the light wasn't turned on?
