It's a simple filter design, it only has a mix, a history and a parameter to control the frequency response. I was asking how could I make something based on this design and make it a resonant filter.

Well, the best results I had was stacking four of these simple low pass filters and then creating a feedback loop from the last order to the first order. It sounds like resonance, but it's not really well tuned and it doesn't sound good. I was asking what was the best way to achieve this or at least some principles I should have in mind.
