Hi hapibeli!
I wouldn't have an awful lot of call for PDF format, but I did see a website, some time ago, that claimed to take a scan of a sheet of music, and create a midi file from it. My ideal would be to be able to take a page from one of the many legal fake books I bought, and scan it in to BIAB. As a programmer, I guess I would try to read the scan, much as you would a page from a book, but instead of translating it into, say, MS Word, as text, it would search and read the printed chords from the page, and proportionally enter them into measures. The vertical bar lines could be one of the triggers for placement, and the position in the bar would be another. This would, however, be an ambitious project, but be quite useful as a tool for learning new songs for the repertoire. Just another thought.
