I have the first Sonata, but of course it would be illegal for me to send it to you... I think your best bet by far would be online music shops. Just google Bach Sonata and you'll have a million versions. If you need them fast, find one that will let you download & print them, not one that comes by post (those hard copies are also more expensive, as you're paying for the "physical" stuff like paper - and for the shipping, which can really be a pain in the anus).
The internet solves anything - again, you can easily find lots and lots places to buy scores online.
@Phlegmak: I don't like that idea at all, to be honest. Have you heard the Adagio of the first Sonata? The rhythm is incredibly difficult, it's impossible to get it right that way! What's even worse is that you can
never know if something is right or not - it's terrible to be insecure about the scores. On top of that, I've never seen any remotely decent MIDI to sheet music converter. Granted, I've never used the software you mentioned, but anything I've tried was so incredibly bad that it would have taken waaaay longer to correct them than to write them from scratch.
Problem is, MIDI files are terrible when it comes to sound quality.
What he's saying doesn't have anything to do with that. MIDI files create computer-generated sounds, not recordings of actual persons making those sounds. Therefore, a MIDI file is a "score" in itself, one that your computer can read to generate music. As such, it can be converted into a "human" score. Problem is, there are SO many inaccuracies that I don't see how it could possibly be worth it.
Especially in Baroque music. I haven't even thought about that, but it's a huge point! The Fugue of the first Sonata for example... it has 4 voices - there's no way for the software to correctly place a note into one voice or the other (or both, as that occurs regularly in this kind of music).
That info is simply not in the MIDI file. And it's reeeeaaaaally important for a player. Really!
