  "provenance": "Original sOURnd design blending general techniques: a sinusoidal phase vocoder on the analytic signal (low-delay asymmetric window, whole-lobe resynthesis of every partial, transient phase reset) driving three voices from one analysis, two-pole low-passes on the voices and an envelope-driven wet compressor. Voicing informed by our own measurements of polyphonic octave pedals (dark subs, compressed octave voices).",
