I'll have a look at the module when I'm back from the Modular Days in
Linz/Austria next week.

> occurs. This is not to be confused with saturation that occurs
> when the input gain is set past 5-6 (a desired effect). This one

> undesired effect. While it may go unnoticed in the busier
> situations, it is very prominent in the more subtle patches. It

> A-101-2 is set up as follows: F/A: 0, Lev.: 4, Res.: 0

> 00:00 Direct sine output from A-110-4. No distortion.
> 00:05 A-110-4 sine out > A-132-3 audio in. A-132-3 CV modulated
> by A-143-9. No distortion
> 00:20 Same patch, A-132-3 replaced with A-101-2 set to VCA mode -
> CLIPPING OCCURS!
> 00:34 A-101-2 set to Both mode - CLIPPING OCCURS!
> 00:48 A-101-2 set to Low pass mode - clipping is barely noticeable.
> 01:02 A-101-2 is replaced with a Malekko Borg 1 set to VCA mode.
> No distortion.

> I have tried adjusting the trimmers to no effect. It is my
> understanding that the VCA is clipped. Even attenuating the
> signal before going into the module or adjusting the Lev. knob
> makes no difference.

> What could be done / upgraded to get rid of this low level clipping

> Thank you very much in advance!
