Hi Jorgen,

In the Notation View, hit the Options tab and in the window that opens, locate the Transpose dropdown near the middle.

Here you can select by Instrument, such as "Bb Trumpet" or you can select by number of half steps.

BIAB will then read out in the transposed key, but still play back in the Concert key.

So if the song is in C, everything but what you hear will be transposed on the notation, lead sheets and chord grid to the key of D.

If you want to have a way for both of you to read together at once, you will have to print out Lead Sheets, one for the Bb and then transpose back to C and read the screen for the C instrument.
