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.    

Thoughts??
