Yamaha CS80

those are most likely key contacts... there are 2  spring contacts at the end of each key... if your key bounces a little, the contact can retrigger especially if the contacts have fatigued and have close  contacts...

This happens occasionally on mine and feels like a weird by-product of double-triggering on a few keys at once, especially when I'm playing a more percussive patch with a fast attack and sustain on. I imagine it's something to do with the Key Assigner... maybe an old CMOS chip in need of replacement. Maybe the multiple double-trigger confuses it? But that's just a guess. 
Some notes on my CS80 tend to double-trigger quite a bit, but it's something I can get around by adjusting my playing style. Seems to happen most often if I don't lift my finger off a key cleanly after playing a note. I've only ever noticed the wonky pitch thing happening under those circumstances. It's almost like the CS80 is making fun of my sloppy or tentative playing ;)

Has anyone had a horrendous change in pitch in one of the oscilators while playing chords with the sustain going? The slider/fader can be as little as a quarter of the way up on the sustain and I get these off-key drifts that make you cringe.
