Yeah - I like that idea, but, I did want to preserve the patch leads as   
you say, otherwise I felt it would lose it's appeal as a patchable   
modular synth. How would you *show* via the front panel the actual   
routing source/destinations with your patching concept? My idea involved   
storing patch info especially for those who spent hours constucting a   
patch but who could never repeat it. It would always default to a   
"manual" mode where it acted as a normal patchable modular on power up -   
the modules just communicate with each other on a digital level, which,   
would be quite transparent to the user.

Perhaps we can throw this into an open arena - list members can put   
forward their design ideas. Even list members who are not very good with   
soldering irons should be encouraged to come forward with their own ideas   
 - some good designs usually come from forums like this. Sorry Stefan -   
maybe I was too hard on you  earlier - you see I'm having a bad hair day!   
(don't ask).
