CWVS, or Cascading Waves, uses a cascade of four interconnected multiwave LFOs, dividers and envelopes to create one unified living control signal for its dirty amp modulation and resonant low pass filter.
As the main feature of this pedal is this controllable but always surprising control signal, it obviously has CV and expression outputs to modulate your other gear.
Sound engines in CWVS are unusual lofi takes on tremolo and filter circuits with the goal of deviating from traditional tremolo and filter sounds as far as possible.
Resonant low pass filter is based upon an old recorder IC not at all suited for the task, but still producing thick saturated filter tone.
Amp modulation or tremolo is based on messing with gain of your signal rather than its volume using choppy optocouplers able to produce percussion rhythms even without any input.
