I have a Korg X50 that has stopped working.
All the displays are fine, and linked up to a pc with a usb cable it works ok as a control keyboard, but no sound is coming from the headphone or output sockets.
I carried out the factory reset as per the manual, but still the problem is there.
I hooked it up to the PC X50 Editor and that is working ok, but as I say, No Sound, the place is So Quiet
