The first (purple) prototype is made. some bugs need to be corrected,
so another proto will be designed.
The current design has these features:
- 3x highpass filter jack inputs
- 2x jack filter outputs (1x inverted, 1x non-inverted)
- normalised feedback routings
- feedback path with VCA (level pot & CV jack)
- voltage shifter with 2 potmeters& CV control (inversion & shifting)
- external feedback is possible
Watch out for video demos! Vidicon21!
This project is my take on the Sandin Differentiator.
