Doepfer

I have the schematics for both the Analog and Digital Oberheim 2-voice  
keyboards if you want to look at them. The digital is pretty  
complicated but the analog one is fairly easy to understand. They are  
on my .Mac public folder:

I understand the lure of analog controllers! Something really basic  
and primal being able to control things with just a battery and a  
resistive element - weather thats a pot, a switch with a resistor, a  
piece of tape recording tape stretched over a metal plate etc etc. All  
fun (and cheap to experiment with!)
