I asked Seth Nemec from Bananalogue about the VCS's response curves and whether it was capable of Linear, Logarithmic and Exponential.
Here's his reply (edited):
"The VCS is capable of all three.
The VCS is a fully authorized version of the Serge DUSG. The DUSG obtained nonlinear responses by feedback patching with banana cables, something that we accomplish on the VCS with the pull pots.
At the bottom of the pot's throw (anti-clockwise) it is in exponential response, bowing up to logarithmic as you turn the knob up (clockwise).
You can read more about the DUSG module in the Serge User's manual written by Rich Gold". (

He goes on to point out the differences between the VCS and the Model 10. The Model 10 adds an "end of attack" pulse out...
"...whereas our original module can also input and effect audio and CV from other modules (allowing for envelope following, low pass filter/gate, harmonic division) and has individual CV over the rise and fall parameters.
Since our module has better CV implementation, it allows for voltage to sweep the response from expo through linear and into logarithmic if desired (makes a nice rich waveform when cycling in audio) rather than using a three mode switch.
so... the answer is yes, the VCS does it and ALOT more ^_^ " (end quote).

Here is a PDF and MP3s demonstrating the above.
