Visual ensemble based on quadratic iterator.
Panel B shows audio signal in X/Y and modulation signal on second display.
Panel A shows controls to tweak.
You do not need to tweak at all !!
... just check the snapshots.
It is based on two quadratic iterator core cells, in which C and dt parameters are modulated by an additive waveform made of three components, each one with five standard waveforms.
Added two resonant filters to keep the whole thing under control.
