Exponential VCA v2164 and CV response

A quick note on the effect of a linear CV on the V2164. I connected a pot between 3.3v and 0. When turning the pot, nothing is heard until the pot is 2/3 of the way to max (CV drops from 3.3 to 0 as the v2164 expects a reversed CV, 0 being max on/unity gain).

Measuring the CV at this point shows as expected, around 1.2V. This means that for the rest of the pot's travel, it has no audible effect. This further strengthens my belief in using linear VCAs for the XM8. Alternatively, one could use a 0 to 1.5v cv, but it will never fully turn off the VCA. 

I'm looking forward to testing the same with a CEM3360/AS3360

Update: This article says that the effective CV range is 2V, which is more like what I experienced:
