Not getting into your three questions yet - couldn't the problem at hand 
(multiple patches) be solved by adding a midi channel selector to the 
MCV module? In other words, if I create a patch with two MCV modules, 
they both take my midi notes from the same channel. If you could assign 
a channel to each MCV, then the network that you set up from one would 
be controlled separately from the other. Thus you essentially have a 
single multiple voice patch instead of having separate patches each with 
its own voice. That would be fine with me.
