11 years ago I created a setter macro for generators which I'll try to check in shortly. Might be nice to use that going forward if it feels good to you. -m-

For now I will add the following filters, which are common in synths:
- Two-pole LPF, BPF, HPF (Butterworth) with Resonance - 12 dB/octave
- Four-pole LPF, BPF, HPF (Butterworth) with Resonance - 24 dB/octave
Both cutoff and resonance will be settable via generator inputs.
This will probably involve a few utility functions (bilinear transform, etc) and a base-class generator for an IIR biquad.
I am also considering a semi-abstract generator subclass for "effects", which may have some common features for generators that affect existing frames rather than generating frames from scratch. Probably will not do this now, but it could be useful in the future.
More filter prototypes for other common topologies to come later.
