Archive of the former Yahoo!Groups mailing list: Discussion about the Korg PolySix synthesizer

I just recently had the battery replaced in my Polysix and had
everything cleaned inside and out, the problem is that say if I'm one
Bank C sound 2, after 15-20 minutes the sound reverts back to Bank A
Sound 1. What do I do?

Any help would be super groovey

Thanks
Joe
