ZZ:
Here's an example of a BIAB demo song in Eb, saved as a MIDI file and opened in Musescore (free notation program).
I think it does a fairly decent job of making a usable notation file.

Yes, Musescore is the way to go if you want good notation at a very reasonable price, i.e free! You don't even need to notate the entire score as all you have to do is to save a track as MIDI and have Musescore score it. Easy Peasy!
