agree with Jim. BIAB is a one trick pony - but it is very able at performing that trick,

Realband is more interesting but for some reason is badly documented and poorly advertised by PG. It is possible to buy your BIAB upgrade and have no idea you have purchased realband as well. Check out the Realband videos in support vs those for BIAB to see what I mean. I think we have realband info as recent as 2014!!!!

Even so it is possible to export any audiofile from BIAB or Realband to melodyne and make as many changes to the audio as you wish.
