Korg wavestate synthesizer, wheel recalibration

Synth Repair

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!

Still need access to the wavestates calibration menu - any ideas?

Have you tried asking Korg for the button sequence?

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