I have a Casio WK 3500 that is acting badly for having live in extreme humidity . So, I bought another one ( WK 3000) which is pretty much the same thing , they share the same user manual. Now , I would like to transfer all my stuff (mainly my user tones) from the WK 3500 to the WK 3000. Is there a way to do it fast ? Isn't this call a "dump" something ? Thanks!
