I own a Kawai GS-40 grand that has a Forte Music MIDI-Mod installed. It dates back to 1989. Some of the key contacts have lost their "bounce". Once depressed, they stay that way. Does anyone have a lead on where I might find these parts? (They look like the flexible contacts used inside office calculators.)

Thanks for any help!

For anyone with a similar problem in the future, here's a followup on this.

I found a complete, unused Forte circuit board complete with the key contacts in the old parts inventories of Southern Keyboards in Marietta, GA. My deepest gratitude goes out to Silas Lyon for his help.

hugo, I bought a Kawai EP-308 Piano, and it has a Piano Forte Midi Mod in it.
Would you tell me what it is used for? I was hoping it is Midi,but it has a 1/4 output jack that says midi out. Maybe it is missing something.

Outlaw,
there is little use in replying to a thread that went dormant seven years ago. Hugo hasn't been seen around here in six years...
