Yamaha CS80

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.
