I have a song which goes from 3/4 time chorus to 4/4 time bridge then back to 3/4 time chorus.

I've noticed that some RT's will follow the tempo changes throughout the song and some will stop at the 4/4, go silent and then resume at the 3/4 time change.

Example that does not follow is RT 615 Harmonica Background HeeHaw SW 165
Example that does follow through is RT 1548 Piano, Acoustic Rhythm Country Sw 085

So why do some RT's follow tempo changes and some don't?
Is there a way to tell in the "Assign RealTracks To Track" window which will, without generating them?

Thanks for any input.
