I've got the tech orientation guide from yamaha for the S10. It's 26.6Mb and in my dropbox. I was gonna post the link here, and will, but I think I need permission. Otherwise, PM me and I'll hand it over.
Can I ask where you got it from. I don't mind following the rules. (Actually, my mom, dad, preacher, principal, coach......all would roll their eyes at that comment)
It just sounds like some good late night reading. It's how I end my day.
