Discussion about the Korg PolySix synthesizer

okay Bob... thanks for the calibration info. It's much more informative than the service manual, i did it by soldering the resistor across the connector pins inside the connector while the polysix was OFF. And then unsoldering it while ON....  So it makes more sense to me why it wouldnt work (unless a deeper problem is still at play here as Roman suggested). Perhaps i shouldnt be trying the calibration routine yet even?
