I still think you underestimate difference in the received loudness 
changes between linear and exponential control.

lets take this graph:

Lets assume you use no external CV and control the VCA only by the 
"Gain" knob.
The X-axis of the graph represents the amount of the gain knob.
The Y-axis of the graph represents the amplification of the VCA.

As you can see at a knob position of "5" will get only 10% of the 
possible amplification. Thet other way around: to achieve 50% of 
amplification you have to turn up the gain knob to position "9" out of "10".


It does not matter whether you are using the gain knob or an external 
control voltage, as the gain knob simply provides internally a control 
voltage.
