didn't DSI run some curtis chips for their new stuff? maybe you can buy in
bulk from them?
or you can use discrete elements and just copy the old moog & arp
filters... those patents are expired now, but several factors would
probably force you to use those designs only as starting points.
and there's maxim -
http://www.maxim-ic.com/products/filters/ i'm not sure if any of those are suitable for synthesizers, but last i
looked (a few years ago) some of them seemed, on paper, like they would

"Under this law (Controlled Substances Act) a bureaucrat -
usually not elected - decides whether or not a substance
is dangerous and how dangerous that substance is. There's
no more messing around with legislatures, presidents, or
other bothersome formalities. When MDMA (ecstasy) was made
illegal in 1986, no elected official voted on that. It was
done "in house." People are now in jail because they did
something that an administrator declared was wrong."
