Any chance anyone's had this problem and knows what exactly the issue is? I've had a Prophet 6 for about two years. Today, I started having an issue where one or both of the oscillators (sounds more like it's an issue with oscillator 1, but hard to tell) plays a half step down every six notes or so.
This started after I was playing with the glide function on. When I turned it off, I noticed the issue. It doesn't happen if I have the unison function on, or if I sync the oscillators. But you lose a lot of functionality with "sync" on, so that's not really a fix.
My guess is something's broken and needs to be replaced, but it would be pretty awesome if that were not that case and I could just figure this out.
