In the linear mode the VCA should let pass no signal if the Gain control is
set to zero and no CV external CV signal is applied (or the CV attenuator is
set to zero). In the exponential mode the situation is different. Please
refer to my message/answer from January 10th 2011 concerning the lin/exp
mode of the A-132-3.
