The example filter core works but it can be a bit unstable at low cutoffs and seems to suffer from some internal clipping. The current implementation is just lifted from the tinysynth project.
This PR replaces it with ladder low-pass filter that should be a bit more stable, allow self-resonance and sound a bit better. Maybe oversampling would be nice as well.
