Although you can transpose audio, I really try hard not to do that because artifacts can be introduced.

Maybe rename the trumpet audio file temporarily, load and change pitch on the other tracks, save that, and then rename the audio file back to its original file name? This makes use of the fact that the audio and BIAB song name must match. It also assumes you already have the trumpet recording in the correct key but the rest of the tracks don't match that key.
