Notes:
Add Vintage Voice Modeling / Per Voice Variance to capture a more organic vintage OBX character.  Per voice variance to oscillators, and ADR timings.   This example patch also uses the synth in bi-timbral stack mode, with each layer hard panned L/R to get a bigger stereophonic/binaural sound.
