Tuning problem / S+H capactiors?

2016-11-13 by dmxkrew@...

One voice of my Polaris is out of tune (voice 1) after perforing AutoTune.

I can also hear a slight portamento on that voice which makes me think the S+H multiplex thing is going on which seems to be a known / common problem.

Can someone point me to info about which caps to check? Should I try reseating the chips as well? Anything else to try?

Thanks!

The capacitors in the S&H circuits are not the kind that fail
and you should not replace them, IMO. If there really is an S&H issue,
it's much more likely to be a 4051 analog switch IC.
