Discussion about the Korg PolySix synthesizer

Hi,
I've searched all I can on this great forum but I still can't figure out how to get by polysix back in tune.  Andrew did a spectacular job restoring the CPU board but now I need to give attention to the tuning board.  I have the service document but can't make much sense of it.  It seems too many things are out of spec to make it work.  There is a post from Johannes stating:

"5.) Now start to tune UNIT0. Take the adjustment procedure as a hint
of what will happen when you turn certain potis"

I just can't figure out what pots to turn to make what happen.  The problem (and I should have stated this earlier) is that an octave in sound stretches more than an octave worth of keys.

Thanks for any guidance or offers of help!
