hey shhboom...Just FYI if you ever wanted, you can put silent switching in old keyboards by use of FET's. Something like a Moto 2N23609. Something like that...not sure as I dont have a cookbook within reach, sorry, Id get up for the book, but I had sugar earlier, which has worn off, and I need a forklift to get out of this chair. Hell, I may even sleep here in this chair tonight. You can use all the original switch hardware no matter how scratchy they are. A couple caps and resistors along with the chip for a circuit about the size of a quarter that switches 4 to (and/or & -/+)1,2,3,4. in total silence. It's a 24 pin I think. Great for pedals too (circuit can fit inside the pedal!)and little boxes that do strange things.
