I personally think a common pin out isn't essential, it woudl be hard to do 
this for a quad VCA, a VCO and a VCF.
I would suggest a common number of pins, say 16, with common spacing, again 
0.1"seems sensible, and with common supply rails +15, -15, +5 and GND. So 
the supply pins are always on the same 4 pins, this would avoid connecting 
stuff upwrong and blowing modules.

I would also like to suggest a common form factor, SIP (a bit like a SIMM). 
It Seems, to me, the most sensible as you can make the SIPs taller and 
double sided if you need to fit more on, without taking more board 
real-estate.
