Korg Poly800/EX800 Users

Hi group, it's been a while,

I have a problem with my Poly. After not using for a couple of months or so, I found out it developed a very weird tune-pitch bend problem. In a nutshell, tune slider seems not to be able to fine tune the Poly but rather it covers almost a whole octave (the default full pitch bend range for the Poly, as if holding down a note with joystick fully to the left and then moving it all the way to the right).

I am troubled since I do have the intention to go install the Hawk mods, but certainly not before having fixed this.

I posted a video in You Tube depicting the problem: http://www.youtube.com/watch?v=JSOtu4YxUCs.

Any and all help to bring my Poly back to normality will be greatly appreciated.

Thanks in advance,

Dave
