Contents
Features
- Similar to Mutable Instruments Branches
- Dual Bernoulli Gate
- Differences vs Braids
- Only has 1 GATE input
- No push buttons
- 0-5V input/outputs
- Built on ER-PROTO-02
- Arduino Pro Mini
= Operation
- Receives single Gate on J1
- RV1 controls OUT 1
- RV2 controls OUT 2
Arduino Pro Mini
Controls
- RV1 - Probabilistic ratio for Output 1
- Center = 50-50, CCW = Out1A on 100%, CW = 0% on OUT1B
- Inserting J3 jack disables RV1
- RV2 - Probabilistic ratio for Output 2
Jacks
J1 - Gate
- 0.6V threshold GATE input
J2 - Random %
- 0-5V control input
- Inserting jack disables RV1
- 0V = 100% on OUT1A, 2.5V = 50% on OUT1A/OUT1B, 5V = 100% on OUT1B
J3 - Out1A
- Gate output 1
- 0-5V digital output
J4 - Out1B
- Gate output 1
- 0-5V digital output
J5 - Out2A
- Gate output 2
- 0-5V digital output
J6 - Out2B
- Gate output 2
- 0-5V digital output
Software
- Arduino IDE
- Pot/GATEs Test
- Reads pots, write values to serial
- Toggles GATE outs - one at a time
- Simple Version 1
- 2 pots, one for OUT1A/B, other for OUT2A/2B
- Version 2
- Adds (2) mode control knobs
- 7 o-clock = 12 o'clock = Normal mode
- 12 o-clock - 5 o=clock = Send Outputs on both OUTxA and OUTxB
