What I usually do is set up the synth, and just leave it on. I had a Juno 60 come in with a fault that took 3 days ( as in on for 24 hours for 3 days) to manifest.... Once it was doing it, it didn't take long to trace it to a dying chip, but it can take a while to dig these things out.I'd leave it the thing on for a few days. Get whatever is being touchy to fail outright... Much easier to pin down then.

I took it up to my repair guy, plugged it in, and straight away each voice sounded perfectly in tune. I got the feeling he may have thought I was just being really picky about the tuning. I left it with him for half an hour and he said it went sightly off while warming up, but he corrected it. I tried it again, and it it was pretty goddamn good across all octaves. So I just brought it home, and what do you know, I plug it in and BOOM, two of the voices are almost a half-step higher once again. What the hell! I tried it on another amplifier in the house in a different room and I get the same thing. I feel like my Polysix is that dancing frog from the old WB cartoon who refuses to perform for anyone but its owner.On Wed, Mar 19, 2014 at 1:10 PM, <swamp.gigs@googlemail.com> wrote:The old version has the KLM 396 on a daughter board mounted on the KLM 366 voice board - the later revision doesn't.
Trimpots 10 and 11 are in the same place on both.
After installing the KiwiSix was the Poly recalibrated ?
If everything is fine other than the tuning of the 2 voices, then trimpots 10 (high) and 11 (low) is what needs adjusted...
