Discussion about the Korg PolySix synthesizer

Cant you just run jumper wires to the need contacts and leave the
damaged traces? I dont see why time needs to be taken to remove the
"balcken'd" area.

I have wondered this myself...everyone said that the acid would spread 
further eventually. In my own case, i did just jump wires at 
first...everything worked for a few months then the patch switches 
started being sluggish and then some started to stay on all the 
time...so I took it apart again, scraped it all out ,restored all 
continuities, replaced IC 31 and ic30....and NOTHING GOT ANY BETTER... 
So i just sent my polysix about 100 miles to a supposed  synth pro 
because i dont understand what is going on anymore....but YES jumping 
the wires did work at first.

Two reasons...

Unless you cut out all the cancer, it will continue to spread.

Even though it might just look like a dead trace, it might be bridging
to a trace next to it.  Sometimes you end up with new circuits being
built automatically by the corosion.

The acid spreads everywhere in the area, you have to clean it all up
when fixing the bad traces.

Can the acid permeate through the middle of the board?  Such that cleaning
the surfaces would be futile?

Incidentally, what is the best method for cleaning (neutralizing the acid
on) the surfaces of the board?

I wiped the area good with rubbing alcohol multiple times.

Technically, you'd need something basic to neutralize the acid.
Alcohol is a good thing to clean an area and dissolve solids and wash
them away.  Of course, rubbing alcohol is acidic (ph 5.5).  If you
really wanted to neutralize the acid, a solution of baking soda and
purified water soaking on it would help.  Of course, after letting it
soak for a while, you'd want to wash it all off nicely.  I'd use
purified water for this.  Let it dry for a day before applying power.

I  had that idea and did that on my polysix...a bakingsoda wash   to clean the battery area, but I cant say it stopped anything from eventually getting worse.(at least in my case)

Hi all!

Just wanted you to know about a midikit for the Polysix that I orded from CHD
Electroservice, a small firm in Prague, Czechoslovakia. Its operation is fairly
basic, but apart from the usual note on/note off-functionality it also has the
ability to sync the arpegiator to midiclocks. Check it out, at the bottom of
the page is pdf for installation and user manual:

http://www.chd-el.cz/index.php?id=399

Swift service, easy installation and the whole thing just costed me 88 euro
(about  129 USdollars) with freightcost included.

So, now my Polysix's got a new life in sync with the rest of my midi-setup...:)

Regards,
Kristofer Ulfves, Uppsala, Sweden

Surely the issue here is that NiCd batteries actually have an alkali 
electrolyte, not acid.... maybe the stuff that leaks out is
actually acidic but I doubt it.

It's still a nasty effect, whatever the chemistry of it is :)

Cheers,
        Robin.

Well, it's an interesting effect that baking soda has... from what
I've read, it will neutralize an acid or a base and produce different
end products for each.  I don't know though. it's been 15 years since
my last chemistry class.

wow, not just that but also pitch wheel! and some other stuff as well...
really good find, if i hadn't midified mine yet, i'd definitely go for this one.

Actually, the pitchbend-option is not that good. Stepping, but that probably due
to it's a PICprocessor-driven application...
