Anyone here know where I could get assistance servicing a WX2 Workstation? Or find someone who can repair it? I have the service manual (schematics), but so far I have been unable to resolve the problem. In some instances it works normally, but on many of the voices, songs, rhythyms, demo, etc. it hangs up after a couple of seconds, sustaining whatever sounds were being played. At that point all controls are unresponsive except the on/off switch. I've tried resetting the system. Until the freeze, everything operates normally - quality, volume, disk drive access, pedals, etc. I'm in Indiana.
