Discussion about the Korg PolySix synthesizer

Hi all,
I just fixed it. Thanks all for looking into my problem. It was a problem with a dataline to the multiplexers. So Simon and Don B( reply from May 15 )  were right ! It was pin 10 of IC 18 that was corroded. By that, P21 ( pin 22 )  on processor IC22 was not connected to Pin 10 of IC18.I tried to repair it in 2006 and 2010 without success. Thanks to you guys it is solved !!Thanks again and greetings from Belgium, Europe.
Johan

    I suspect some address lines not connected to all the 4051 ic's
