let’s see if I can describe it better…
so, I have a song, 4:00 in musical length. I set the “project length” in the Project dialogue to 4:10 to give me some extra room at the end of the song so I can better see the end of the last clip better, and also so when I zoom-out in full I see the entire song fitting on my screen.
But sometimes when I open a project, the actual time-allocation in the Project dialogue has gone from 4:10 to, in this case, 9:40 so the “playing field” has doubled in size.
The song and markers and locators are all where there supposed to be within the clips-range, but the total-project-time has jumped way up and there is now a long stretch of blank bars after the song-end.
Weird, huh?
