What about incorporating a small uC in every module and have a 
central module just collect the data and save the patches via some 
sort of serial bus? Every module has its own id number so you can 
connect modules to the bus as you make them. A patchcord system can 
be accomplished by pressing an "output" button on a module and then 
an "input" button on another. Every module has a digita bus 
and say eight analog buses to route the audio and control voltages.

I and Magnus D have been talking of this a few times i think. I will 
probably never attempt this, i stay analog for the patching!

/d - thinking out loud
