I have spent a lot of time looking for the best available filter in VCV for pinging. Until recently I had settled on the Vult Unstabile.
But ever since I created the Venom Multimode Filter, that has become my go to filter for pinging. It is an absolute beast, yet will never self oscillate unless feedback is applied. To get the widest range between short resonant clicks and long ringing pings, set the resonance to full, and then apply more and more feedback until it starts to self-oscillate. Then back off the feedback until it no longer self-oscillates. The optimal feedback level is dependent on the chosen filter slope. The higher the slope, the less feedback you want.
Now simply ping away. Adjust the resonance to dial in the sound you want. The entire resonance range is useful. It has a huge range both in terms of frequency, and ping character. Also play around with the gain. Set it just above zero to get a delicate ping, or pump up the gain for some delicious saturation. Currently the gain is capped at 2, but I have an updated version that I plan to submit to the library that goes up to 10.
My favorite setup is to use the 24 dB/Octave slope, with feedback set to ~0.223
Lastly you can play around with the Spread, which applies different cutoff to the left and right channels. Set the Spread mono mode to subtractive, and patch only the left input and the left LP output. The filter subtracts the right from the left to effectively give a band pass filter with two resonant peaks - very satisfying! This is basically the technique used by Rob Hordijk in his Twin Peaks filter, except I believe he used a ladder filter, whereas the Venom filter is a digital implementation of a state variable filter. It works just as well with BP and HP outputs, with slight differences in character.
