Hi Dave. Welcome to the forum.

My experience when importing MIDI to BIAB is that BIAB surmises the key, which you can change (without transposing) as you wish.

I'm not familiar with Sibelius, but I think the actual chord designation from that program will not be part of the MIDI file and so wont make it into BIAB. If that's the case, you will need to type the chords into BIAB, or let BIAB take a shot at divining them. The success of that is dependent on the fullness of the MIDI arrangement and how "standard" the tune is. Sometimes good, sometimes not.

There are others here that use Sibelius and can perhaps speak more authoritatively.

Good luck.
