Subject: Tuning issue.

Hi,


I've got Korg Polysix here, with clone KLM367. 


There's something wrong with tuning. C-keys are something like F and octave is couple semitones shorter than it should be. It's impossible to get it tuned right. I've been following several calibration instructions without any success. 


VR2 has no effect at all.


Is it photocoupler? IC18 pin 7 gives +12v. As I understood it should give something like -2v - -5v, but this one gives something else..
