I'm angry too Roel,
I live in Italy and it is really a shame that after one week I did not get any reply to my email: I owned a Korg I30 for five years and never faced problems of this kind...

I think SD1 is a great keyboard but you cannot buy a car if you are not sure about "aftersale" service...

I wait for the new G70 and possibly I'll move to her...

Ciao

Gabriele
