Discussion about the Korg PolySix synthesizer

To troubleshoot the "staying in reset" issue when you try to do the procedure in the manual,
put your meter on the 5V supply at the KLM367 board and watch it when the 56 ohm resistor 
is connected and disconnected.  It should be dropping by a noticeable amount when the resistor
is connected, and then changing back when the resistor is removed.  

BTW, the first step, I think, is setting the supply voltages after giving things a chance to warm up.
Did you do that one?

       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?
