Korg Polysix and Poly-61

2006-11-09 by sputnik979

Hi guys,

Both synths have been through the battery leakage and subsequently 
extensive cleaning, resoldering etc. Both work fine apart from the 
memory. To put it in plain words - the memory seems to remember only 
certain parameters. In Poly-61 it recalls filter cutoff, resonance, 
modulator settings, but not the envelope. I've created a patch with 
long release but after recalling it the release is gone and the 
envelope is in GATE mode. In Polysix similar problem but more extensive 
and complicated. Can you pin down, trace the problem to a specific area 
on the board, some component? I have no idea where to look, we've 
looked at it so many times... 
thanks
