  "provenance": "Original sOURnd design blending general techniques: a sinusoidal phase vocoder on the analytic signal with a low-delay asymmetric window, whole-lobe resynthesis, transient phase reset and cepstral formant keeping (poly mode); pitch-synchronous overlap-add grains driven by a YIN tracker with full-rate refinement (mono mode); equal-power panning, per-voice delay lines and a soft-limited feedback loop through the shifter. Ranges informed by our own measurements of octave and pitch pedals.",
