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.
