Discussion about the Korg PolySix synthesizer

Actually it's fixed now. There was acid-trace in KLM-366B. It's is now in tune, but there's something that causes slight but very audible  fast modulation in higher octaves. It seems to be connected with antilog somehow, because when turning on Polysix, pressing few keys to hear that "warm up sweep", the notes are absolutely clear. But when it goes to "stable" mode, the modulation starts. I noticed that sometimes it will go away after 10 minutes, or sometimes it will stay without fading away.
