So, I want to make a Differentiator pcb with additional voltage controlled feedback.
I normally feedback it with a summing mixer, but I think CV control will make it even more interesting.
The effect of the feedback is that the edges repeat themselves several times until chaos ensues.
I paired the Cadet Multiplier schematic with the Differentiator and changed some stuff
The design is not finished yet and must be tested.
Right now I’m thinking 1 pcb for pots and jacks, 1 pcb for the main circuit and a panel pcb.
All sandwiched together to decrease depth. 8HP if it fits
- feedback path switch (normal / inverted) - be to tested
- 4 edge filter inputs (instead of 6) - to save space. If it fits, this can be changed to 5 or 6.
- switches for feedback routing
- not added yet, but interesting: diode clipping distortion or more filtering in the feedback path?
example of feedback edges: (in a patch, no cv yet)
The white dots = edge of the green shape routed though a Differentiator and feedbacked with a modified summing mixer.
(red & blue channel = camera feedback)
Remark: this project is directed towards DIYers and will be open source.
