Korg Mono/Poly

Hi guys,

I made a recording of the problem-M/P tonite:
I tried to capture the noise by doing the following:

first, all OSC off, and filter Cutoff & resonance set to 0; VCF Env 0, VCA attack 0, dec./sust. mid, short release; No additional noise or any fx;
playing a pattern C3 A2 C3 C3 A2 C3
then I first turn up the 16' sinewave, after that the 8', the 4' and the 2', and then the cutoff a little bit, as well as the VCA release...

hope you can hear the noise / distortion, sounds really strange to me - none of my other synths have anything like this, and as far as I remember the M/P didnt have that earlier (didnt use it for quite a while...)
earlier I used the M/P with 1 sinewave for heavy baass lines, dry stuff, without any noise at all... now I cant get any nice sound of it anymore without that noise... :( 

any idea off what this could possibly be?
how can I track down the fault?

thanks & regards
mark
