Whether not weather.

1. Get a notation software program. There are free ones--maybe Noteworthy? I use Sibelius and there is also Finale. A shorter and cheaper version is PrintMusic ($49?). You can transpose and print from these pgms.
2. Enter the notes. You can choose which ever instrument you want.
3. Save/Export the file as a midi file.
4. Open midi file in BIAB
5. Quantize, using melody drop down menu in BIAB, as you choose.

Sounds simple but it will take you a little time to learn. The time is well-spent, IMHO. You can also enter notation directly into BIAB, but I can't tell you how to do that. Hope this helps....well some anyway..........
