Sorry, hit the right key at the wrong time ! Maybe this has been covered in the technical discussions up above, but what I would like would be to scan in music notation from a book or sheet music, or other source and then hit a key and hear it played back.

I realize this is tough because of all the differences in staff size, notes, etc., but as an "ear learner" rather than an "eye learner." This would be a neat way to learn tunes that I now only wonder about until I can find a piano player to do them.
