Someone did something to my KORG Music Workstation 01/Wfd. None of the combination sounds work. It sits out at church (I think somebody was playing with it). All the sounds in program mode work. Any help would be greatly appreciated

go to the Korg page at synthzone.com. You might find help there. At the very least, you will be able to download all of the patches and combis and reinstall the originals. You will also find tons of new sounds to download.

This sounds like someone changed the GLOBAL MIDI Channel from 1 to other channel. The Standard Combis are set to sound on MIDI Channel #1, so they will not sound... My suggestion: Search in GLOBAL mode the setting for the global MIDI Channel and switch it back to 1.
