Hi Dave,
I've got a similar problem with my VCO4, but it is only out of tune by about 1/2 semitone. Being so small, I can still correct it with the tuning knob.
The weird part is that it happened all-of-a-sudden, not gradually. And, occasionally, it plays at the correct pitch for a while before stuttering down to the ~1/2 semitone out. Weird.
Did you ever figure out your problem

I did hear them step back in tune but it was quite brief and then they abruptly went out of tune again. Is this a take it to the synth repair guy thing or something I can remedy with my own fairly limited electronics knowledge
