PItch bend wheel emitting values by itself

  • Hi all,


    The pitch bend wheel on my Virus TI2 keyboard has started to emit random values without me touching it.


    What would be causing this? Is it probably dirty contacts in the wheel potentiometer?


    If it is, I'd like to try to clean it myself before handing it over to the service center. I have opened up and worked on many synths over the years. I am unable to find any clear instructions on how to get it open, so I would appreciate any links or pictures that anyone might have.


    Also, is there a way to turn the pitch bend off so that I can at least use the Virus for now? It is my main control keyboard and is sorely missed...


    Regards,


    D.
