OK, I understand the idea of the VCM now, but if that is so, there is
still a problem of mod depth for each juction. A simple VCA in
socket would not allow for CV attenuation as the A-100 envelopes and
LFOs have no level control by themselves, and even if they did one
would have to trim that CV out to all destinations which defeats the
purpose.
So would each juction have a pot and socket That would certainly
increase size/cost. However, if it was left at just VCA in sockets,
one could fit 8x8 in a 3U space just like Multiple 1, only it would
take about 50 HP to work. I don't think that is cost effective for
rack space....a G6 is expensive.

This brings me back to my previous post, why not a stand-alone unit
You could even have all functions in one (minus pin matrix), by
having four audio ins with pot junctions, four linear ins with pots,
and four VCA ins with or without pots.

Perhaps a package deal from Doepfer with a simple matrix MIXER and a
few A-132 VCAs to use as you like, OR the VCM plan with just the VCA
ins at junctions packaged with an attenuator module like the A-
129/3.
