MOTM

I *deeply* apologize for being completely off-topic here. But I have a
vexing problem, and I figure... here's a bunch of really smart, experienced
people well versed in music electronics... I just had to run this up the
flagpole. Please forgive me.

I have a Korg Mono/Poly that has for some time been exhibiting bad contact
on many of its keys. The problem has grown slowly worse over the last five
years. I opened it up expecting to find a Pratt-Read-style wire & rail
keyswitch mechanism, something I could clean, but instead found this odd
contraption where the keys have little gray 'suckers' on them that press
against a PCB. I never saw this design before and was afraid to go wiping
alcohol all over the place without knowing what I was doing.

Do any of you have suggestions of what I might do to clean up this type of
keyboard? I don't quite understand its principle. I'd like to use the
Mono/Poly to control/interface it with my MOTM system (whew! I snuck a
little topic in there! Saved!). Thanks in advance for any wisdom passed my
way!
