Repairing Korg MonoPoly keyboard contacts

Korg MonoPoly keyboard contacts, originally uploaded by olilarkin.

I had some keys not triggering on my Korg MonoPoly - a common problem with this and other synths of the era. I cleaned the contacts as per the old crow tutorial (twice) and still some of them didn't work - I guess the conductive rubber had just worn away. Thanks to some advice from the Analogue Heaven mailing list I applied some conductive paint to the contacts which seems to have done the trick.
