Hi icelander, I hope this answer your question. I have tried this before since it is an issue trying to use better sounds as you said. When I apply a harmony to an instrument I export that track to a midi file or use the drop feature in BIB, then I bring that midi into my DAW (I use Sony Acid Pro). I should come in separated by tracks including the main instruments and the harmony ones whatever they may be. There you can use your favorite VST or Softsynth. Works for me.
Take care.

Mike B.
