One nice way to build the ‘waves’ is to map the Resonance to an expression pedal or HotKnob. Then bring them in & out from zero to extremely Negative (or Positive) resonance. I’ve made a sequencer with deep filter sweeping in that way.
Another thing you might try is putting Harmadillo in front of the Resonator. Sync the tremolo speed to the resonant ‘notes’, and accent them hard with a Pulse Shape. The notes will start to blur when you switch Shapes to a Sine wav, for example.
