Hey Y'all,
All of a sudden OSC 2 and OSC 4 won't stay in tune. On certain
octaves one or the other will stay in tune but if you go up or down
they gradually begin to drift. For some reason, keeping the effects on
seems to help a bit but I don't want to use X or Frequency mod 100% of
the time...totally sucks.
I always let my Mono/Poly warm up for 20 minutes at least before
I even touch it, and after that OSC 1 and 3 stay perfectly in tune.
This is really frustrating, since I've only had this synth for 6
months and it worked fine up until just recently. I'm very gentle with
my keyboards and don't have problems with any of my other synths. Has
anybody out there had this same problem I know nothing about
synthesizer repair so I also need to ask if this is repairable or if I
am screwed. Any and all help or advice would be greatly appreciated!

Thanks, everyone!
