The Documents Library brings you service documents, schematics, and tips for keeping your synthesizers tuned up and ready to rock. One of these days I'll get all my schematics and service docs scanned in, hopefully along with some user manuals. But until I get fired or layed off and find a few free months to scan them in, this will be the world's smallest service documents library.
