And one more experience:

Loading the autotalent plugin in all 5 slots of an unused audio track
(5 times to maximize the effect) leads to a delay of the MIDI-tracks
but not of a used audio track, so the vocals have a negative delay and
set in too early.

I think there is a kind of magic built-in in Rosegarden with some little
errors in it.
