Patches and discussion for Ensoniq VFX family

Hello everyone-

Does anyone know any good fixes for buttons that stick on a VFX-SD?

The first button to stick is the top left "soft key" - it seems hung up in 
the hole in the display. I tried using the corners of a laminated card to 
clean out any buildup in the crevice, but it is still sticking. The other 
buttom which is starting to feel sticky is the "Sounds" button.

I read on www.hometown.aol.com/mishon66/ensoniqpage.html that there was an 
article in Electronic Musician Magazine in the June 1990 issue, page 80 
which addressed "VFX buttons stick", anyone have old back issues of this 
magazine?
