Thumping filter in a memorymoog

[Gerry Dahl]

Hi Everyone,
I have a Memorymoog that 1 voice is thumping on when I play a note on it.
I removed the line cap (between OSC. output and filter input) and it still
does it. I've tried a second cem3360 VCA chip but that didn't change anything
either I adjust the VCA trim but it just seems to go to a deeper (more bass)
thump. 

Any ideas on this would be great.
I have lots of the right tools so throw any ideas at me.

Thanks.
Gerry Dahl
