Yes, that works... in the circumstances where you have CV on a
parameter... though you'll often find a lot of parameters,
**especially** on the more compact and budget conscious modules one
is likely to think about when trying to build up sets of matched
modular voices.

Looking at the history of polyphonic synths you can see that the
advent of synth chips like SSM and CEM to a substantial degree
enabled polysynths because they had CV on nearly all their parameters
and they allowed smaller and (hopefully) matched systems with
multiple voices. Unfortunately imho the demand for an affordable
simple patchable analog synth winds up conflicting with the CV on
every parameter which in my mind is a necessary feature for a
satisfying attempt at making a poly modular.

A-132-2 or the forthcoming A-132-4

There are certainly some uses for the A-132-2 but it's not going to
deliver 4 independent VCAs. At first it looked really neat to me and
then I realized except for the CV input pots, a pair of dual VCAs is
in most cases more flexible in the same space because you can get the
same effect by multing the source voltage to.
