But that's not the point of today's post. Let's start simple. Let's fix the dead keys...
Out on the web, one can find a bunch of approaches to fixing dead keys on old keyboards. The best description of how to work specifically with these old Korgs is from Old Crow...his site is really good...you should check it out...
His text and his pictures give you the confidence to dive right in, even if you (like me) might not have ever done anything like this before. Very inspiring.
Unfortunately, following his directions for simply cleaning the key contacts didn't fix my dead keys. Bummer. After a bunch more internet searching, I came across a reference to this paint-on electrically conducting stuff...CaiKote 44. Oh man, this is where it's at...
A little of this stuff goes a *long* way, so all you need is the tiny little package shown on the left (not the bigger tub on the right). To use this stuff, simply: (1) follow Old Crow's description to get at the keyboard's rubber contact strips, (2) swab a very thin layer of this CaiKote stuff onto each rubber contact, (3) let it dry, (4) put your keyboard back together. Voila!
After applying this stuff, all the keys on my Mono/Poly worked. Outstanding. After I got my Korg Polysix off eBay, I found that it had a few dead keys, too. I dug out my several-year-old tube of CaiKote 44, put a little bit on, et Viola encore! This stuff is great.
Oh yeah, for those of you on Muff Wiggler (an excellent discussion board), I discussed this fix in this thread: http://www.muffwiggler.com/forum/viewtopic.php?t=71861
And I just found this...another guy who used CaiKote on his PolySix. He's got great pics:
Update: I just learned that LASynthCo is selling newly-manufactured key contacts for the Polysix and Mono/Poly. They're not super-cheap, but it's a great option to have. http://shop.lasynthco.com/product/key-contacts-for-korg-poly-oberheim-sequential-prophet-600-kawai-and-others
Update: As some of the keys on my Mono/Poly have stopped worked again (I guess the CaiKote is only good for a few years), I bought some new key contacts from LA Synth Co. They work great! You can check it out here.
