Quadraphonic Bass Experiment: Synced Oscillators Per String + High E String Filter Sweeps Low E

This was an riff/experiment I put together using my quadraphonic bass (see https://www.youtube.com/watch?v=PgDSz1GCK-I&t=5s for a gear run down). Using the Cycfi pickups, each string's output is being routed through Audulus. Low E, A, and D each control the sync of a square wave oscillator for crude/distorted pitch tracking and the "volume knob" of bass, which outputs a velocity CV, controls the oscillator frequencies. Since the sync is providing pitch, the frequency kind of controls the first harmonic, so twisting the volume knob provides a filter sweep effect. Getting nerdier, I'm using pitch tracking on the high E string to control a conventional high-resonance filter sweep on the low E string, so as I tap the high e string, the filter on the low E "drone" dances around. Finally, the tone knob is emitting a midi CC that I'm using to roll in reverb on the whole mix.
