I didn’t realize there were clip plugins involved. That does complicate things.
I went on and on about this in another thread:
I need the clips to stay exactly the same, but you need the clips to expand with the soundfile. I’ve asked for an option to have it either way. As it is, clips shrink with shorter files, but don’t expand for longer files, which makes no sense at all to me. You need clips to expand and everything to the right to shift to fit it.
If you’re generally dealing with longer new files, I think the only thing you can do in 7 is temporarily save the original clip plugin chain, and then load it in the new clip. I would make a new temporary track (track 2), put the new clip on track 2, select it and ctrl-c (copy), then select the old clip on track 1, and ctrl-v (paste) with the paste option that moves everything to the right (don’t remember exactly what paste option that was, “replace with shift” or something like that).
