Hello Andy,

the gain knob and the CV inputs behave in the same way. The voltages coming
from the Gain control and the CV inputs are just added and the sum is used
to control the exponential VCA based on the THAT2150.
In other words: if you move the gain knob uniformly from fully CCW to fully
CW it's the same as if you apply a linearly increasing CV from 0...+5V (with
appropriate setting of the CV attenuator).

I'll send the documents to your email address.

Best wishes
Dieter Doepfer
