[Stk] STK Filters + Third Party Classes

[Ross Clement]

Hi all. Two questions here as I'm trying to keep the number of
beginner's questions down.

First, what is the best approach in STK to implement "normal" resonant
lowpass, bandpass, and highpass filters. I have looked through the
standard STK filters, and while I can see how to use them, there isn't
anything obviously sweepable four pole filter with methods to set
frequency and resonance. What do people do when they want a
"traditional" filter sweep.

Possibly related to this, are there any major repositories or sources
of "third party" STK instruments/classes? I can't find mention of this
in the links or FAQ.

Cheers,

Ross Clement
