Hi all, I had to replace the 10 KOhm Modwheel potentiometer; mow I need access to the service menu, as there is a calibration function. But how could this service menu opened? I think, it’s a 3 button combination … Anybody here who can help? Thanks a lot! ---

I asked Korg USA and another Korg support … they refused telling me the button sequence but confirmed, that the wavestate has a calibration menu.
