Discussion about the Korg PolySix synthesizer

In recent years I've noticed that my P6 takes quite a while to to warm up and get in tune. I read some older posts here and it sounds like 10 seconds is normal. Mine takes longer, maybe a minute, but it's more like a slow VCO LFO rather than individual notes being out of tune. My gut would tell me to start replacing capacitors but I haven't pursued it and I'm not sure how it would affect the sound by doing that.

Also - generally speaking the synth out of tune and is off by a semi-tone or so. I've got my tune knob all the way to the left and I imagine it'll get worse over time. Note for note the synth is ok so the calibration appears to be normal, but as I said, overall it's noticeably out of normal range.

Thanks everyone!
