VCF using modern parts

I'm thinking about how to build synths with modern components.  Main
problems are the VCF and envelopes.  Oscillators might be best done

I found some SSM2164 quad VCA under the dust which I think was planned
to be used as such before I forgot about them.  How to use these as
VCF?  Maybe the datasheet has some circuit?  No.

This has [3].  Maybe a single SSM2164 can be used for a 3-pole SVF and
a VCA?

The SSM2164 can run on a single supply down to 8V using a VCC/2 opamp
buffered reference voltage.
