Today, I changed the audio of one of my songs in audacity (made it 15db louder) and then opened my LSP sequence and replaced the song and saved it. I then deleted that song from my schedule, clicked o.k. and then went back into the schedule and then re-added the song. During tonight's testing, the first 3 songs played o.k., then when it came to this sequence, the music played but no lights showed up. After that song finished, the schedule continued on it's merry way with lights on again. Is there a process to replacing/updating the sequences in the scheduler? I've just made another small change to another song that I noticed now (RGB channel orientation on 1 element), and I'm going to try deleting the show, then deleting %temp%\* and then I'll re-create it.
