Well, it's way over my head. I get an idea of what you are up to but I have 
no clue as to how to help. There are a handful of EML schemos in our files 
section if you care to take a look but I don't know if they apply.  I'm 
just not into the technical end of it much. I'd hope other members 
here  might have some answers. Of course your inquiry is welcome here but 
if no one replies, you ought to try asking at  the Analog Heaven list or 
maybe even the synth diy list if it's still around ...good luck!
