Doepfer

I just looked at the Blacet site, and it doesn't look like the 
Klangwerk has a "ring-am-pass" control.  But it does have a switch 
to make it DC coupled, so it could be used in place of the PAIA in 
my original example.  
Too bad, since the Blacet could certainly be squeezed into a Doepfer-
style face plate.  Not a viable option with the Buchla or Serge.
