Hi, new member here.
I have an Oberheim 4-voice (Believe it or not, I’m the original owner). It seems to have recently developed an issue with one key on the keyboard. When pressed, it intermittently will do a thing where it jumps between the SEMs. I’m guessing this strange tracking behavior is some kind of physical contact issue. I’m a musician, not a tech so guessing is the right term.
Anybody have any ideas what might be the issue? How big of a job would accessing the keyboard mechanics be? Since they are basically on and off switches, I’m thinking it isn’t making a clean contact.
