Overview
A dual logic processor for combining gates and CV. Pick a mode and the two outputs give you the complementary pair — AND with NAND, OR with NOR, XOR with XNOR — plus COMPARE, MAX/MIN, and FLIP-FLOP. Inputs A and B can come from the panel knobs or the CV jacks.
Panel & I/O
| Control | Pin | Function |
|---|---|---|
| POT1 | A0 | Mode — logic mode select |
| POT2 | A1 | In A — input A value |
| POT3 | A2 | In B — input B value |
| LED | D3 | PWM output A |
| F1 | A3 | In — CV input A |
| F2 | A4 | In — CV input B |
| F3 | D10 | Out — PWM output A |
| F4 | D11 | Out — PWM output B |
Features
- Six logic modes: AND/NAND, OR/NOR, XOR/XNOR, COMPARE, MAX/MIN, FLIP-FLOP
- Complementary outputs on F3 / F4
- Panel or CV control of both inputs
- Works on gates and continuous CV alike
