Thought this newly released VST might interest some here due to its internally semi-modular nature (and some cool examples of nonlinear filters and other filters with some unusual characteristics/parameters, like multi-point resonance, Q-up/Q-down, etc.)
The demo video has some neat EQ tricks that could be replicated in VCV Rack without a lot of trouble.
