[sdiy] analogDNA

[Paul Maddox]

Rob,

this sounds familiar :-)
http://www.modulus-music.com/concepts/digimod/

I speant a long long time working on the whys and wherefors of different 
technologies for this, sadly a lack of time and money has prevented me from 
doing this.
Rainer Buchty and I also started working on this together, but again, we 
both ran out of time and money..

It's almost the 'holy grail' of modular synths in a way, but, be prepaired 
for a lot of analogue 'purists' screeming "NOOOO" because of the the word 
'digital' in your proposal :-)
