I'm in a bind.  I'm working on scoring a film and I've already created a few clips of music parts 1/2 way through the video. In order to write the whole thing, I need to make changes to temp and time signatures (no problem), but I want everything I've already created, to lock to the exact same HMSF time they they are already placed at. Meaning that these elements are already synced to the film visuals. Not that it matters, but I've already synced some creepy horror risers and what not.
