  "provenance": "Original sOURnd design blending general techniques: a pitch-tracking low-pass (YIN tracker) ahead of a Schmitt trigger with envelope-relative hysteresis, two toggle flip-flops as frequency dividers with polyBLEP band-limited edges, envelope scaling with a soft gate and a two-pole tone filter. Voicing informed by our own measurements of analogue-style octave pedals.",
