Korg DW8000, Mono/Poly, MS-20...

No, that's not a stupid question, I was thinking of the programs I
reloaded to be the cause of my problems, but I reloaded them several
times. And it was not just one set of programs but a few - I took them
from Bryan Ressler's web page. The effect is still the same. I also
cleared memory several times (buttons 5,8 during restart). But I think
 the value for Release parameter you wrote about might be the point
here - that's my suspicious as well - and I also think of VCF
Resonance as of another cause of the issue. The problem is that both
things are being realized by NJM2069, as far as I know and if that is
true and the one is damaged, then I am simply defeated. But on the
other hand there is rather small possibillity that each and everyone
of the 8 NJM2069 on the board is damaged, is not it? Yet each voice is
affected by the issue.
Anyway, thanks for the advice.
