I hope I’m missing something, but is there a simple way to select portions of your entire project and move everything in that section (all automation, including automation that isn’t tied to events on channels like Sends and Groups)? Yes, I know that automation tied to events works for tracks with events, but sometimes a track doesn’t have events on it for certain reasons (i.e. you deleted the part but you still want to move the existing automation on it), and again: Sends, Groups, and Master faders have no events that they correspond to.
The only way I know of is to “Show All Automation”. The problem is that it’s an extra step that I’m hoping is not necessary, and in addition to that, when you “Hide All Automation” afterwards, all the Groups and Sends and Instrument tracks with more than one output get hidden for some reason, so you have to go and re-expand all of those sections, which in a 500 channel-plus scoring session (with tons of automation) can take a while.
