Dan01, I wouldn't buy a keyboard from the internet...

Roel, I was talking to Dan01 about the "crazy keyboard buyer".

About the keyboard... Yes I opened and I fixed that little spring in 5 minutes. The problem was to open the keyboard!

By the way, I sent a mail to Ketron and they answered me the next day morning(monday)... Nice support...

Dreamer, thanks a lot for the help given! If it wasn't you I think I would unscrew the wrong screws!!

Ok people, it's done, thanks everybody!
