I recently purchased a songbook which comes with a CD of backing tracks (NOT BIAB-compatible), in which you play-along from written sheet music in the book. (I play piano/keyboard.)

I like the concept, and would be interested in purchasing others in the series, except that some of the songs are written in difficult keys for me (ie - 5 sharps, 4 flats, etc).

It would be great to be able to transpose these to an easier key. I already have software that can transpose the audio files on the CD to any key (and slow the tempo), so I'm already covered on the audio side. However, is there a way to perhaps scan the written score and then have it also transposed (for re-printing) to match that easier key? I know that I could do this by hand, but it would be quite tedious.

An ideal solution would be software that would load/import a scanned PDF (preferably multi-page document) and convert it to Music XML format. From there, I have software which can transpose the written score to a key more compatible with my meager piano skills and export it back to PDF for display on my iPad.

This is probably a lot to ask from software, but thought I'd pose the question anyway. Of course, it would be best for me to learn and get comfortable with playing in ALL keys, but I'm not looking to become a pro. I just want to be able to learn to play some songs from written scores that I already have, but happen to be in difficult keys (like B major, for example).

I'm running Windows 7, if that matters.

Any thoughts/suggestions on getting this done would be greatly appreciated!

Thanks.
