...it was always my understanding that a track can't "play" if there's nothing left to play, hence the condition of which we speak.
Hmmm. Maybe I can't say for sure why things work for me the way they do. But here's a bit more detail of my usual routine:
--I always have track automation, and am not concerned with the behavior that a project keeps playing past it's actual ending. So that's why my tracks keep on playing - there are some nodes way out there in right field.
I select the part of the project I want, cutting out introductory measures, and leaving plenty of time for FX to die out. I'm not too concerned with precision on the selection because I always do final touches in Sound Forge, tightening up the ending if it's needed, for instance.
All I know is my FX always fully ring out - whether or not it has anything to do with the "play tails" setting--I always thought it Did effect that, but it's making sense that actually that's not involved, and that's why the original topic of this thread was about something else.
But, that's why my tracks play past the end of the last clip's length - the automation nodes. And of course there's still sound bouncing around in the reverb units, so that plays out.
