Discussion about the Korg PolySix synthesizer

Hello all, I wanted to add to this thread, I tried this method 
tonight and it worked wonderfully! All the keys that were not playing 
before play just fine. I needed to double up the foil on one key 
since it didn't play still afterwards but with an extra layer of foil 
it worked great. 

I only applied the foil circles to the keys that weren't working, I 
let the other working contacts be (if they're not broke don't fix 'em 
kind of thing)

Anyways, wanted to say thanks for this tip. I'm back in business!
