+1 if possible.

There are workarounds to this problem. One could export the stems (the individual audio tracks) to another program to change the pitch. Programs from the free Audacity to expensive ones like Studio One Pro or Melodyne will do this.

BUT the problem with changing pitch, even if BiaB can do this, is that if you get to far from the original pitch one can get artifacts. The most expensive the program the less artifacts one can expect but if you are only going to change the pitch a third or less then Audacity just may work. It's free so give it a try.

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.
