[chuck-users] driving filter frequency from an envelope?

What's the chuck'ian idiom for driving a filter frequency from an
Assume I have a primary signal chain that looks like this:
Blit b => ResonZ z => Envelope e1 => dac;
And I want to drive the center frequency of the ResonZ with another
envelope. I know I could do it something like:
Phasor constant => Envelope e2 => blackhole;
... and pepper my code with short delays that update the resonator's
.01::second => now;
z.freq(e2*440.0 + 100);
but that seems both inelegant and computationally wasteful. I've
looked at the .op inputs -- that may be the answer, but I can't quite
tell from the documentation.
So: is there a way to directly control the resonant frequency at the
UG level without breaking back into "user code"?
