Here is my first attempt at making a resonant lowpass filter using cpole~ and czero~ objects. It's the first version I've made which actually sounds halfway towards what I want to achieve, which is a decent diode-ladder or transistor-ladder filter emulation. I want to make this using only vanilla objects, particularly rpole~, cpole~ etc. so that they can be ultra-portable and signal-controlled.

Does anyone else have any ideas, or patches we can share?
Most filters in the rj library (https://github.com/rjdj/rjlib) use a similar approach. They even include a biquad-clone written with elementary filters. Some are modelled after the classic reson-filters used since CSound times.
