Amnis
A shift-register-based generative module that produces 8 gate outputs and 4 CV outputs (3 staircase, 1 slewed) from clock and data inputs, with an XOR input for linear feedback and compatibility with Turing Machine expanders.1115
Capabilities 4
- Noise Generatornoise-generator
- When clocked at audio rate with XOR feedback from Gate VIII, the module operates as a digital noise generator.1115
- Random Gate Generatorrandom-gates
- Produces 8 independent clocked gate outputs whose pattern is determined by the shift register content, with optional randomization via XOR feedback.1115
- Random Sourcerandom-source
- With the XOR input patched for linear feedback, the module generates pseudo-random sequences of gates and CVs.1115
- Shift Registershift-register
- Acts as an 8-bit digital shift register clocked by the Clock input; each bit is individually available as a gate output and combined into staircase CV outputs via R-2R networks.1115

| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (4) | |||
| Clock | clock | — | Clocks the shift register on each rising edge; comparator-based input with threshold around 2.5V.1115 |
| Data | mixed | — | Feeds values into the shift register; accepts any signal and passes it through a comparator with a 2.5V threshold.1115 |
| Reset | gate | — | Empties the shift register when driven high; comparator-based with a built-in gate-to-trigger converter so only the rising edge triggers the reset.1115 |
| XOR | mixed | — | Second input of the dual-input XOR gate that combines with the Data signal; enables linear feedback shift register behavior.1115 |
| Outputs (12) | |||
| CV All | cv | 0V to 5V | Staircase CV derived from all eight gate outputs combined via an 8-bit R-2R resistor network.1115 |
| CV Even | cv | 0V to 5V | Staircase CV derived from all even-numbered gate outputs combined via an R-2R resistor network.1115 |
| CV Odd | cv | 0V to 5V | Staircase CV derived from all odd-numbered gate outputs combined via an R-2R resistor network.1115 |
| CV Slew | cv | 0V to 5V | Slew-limited version of the CV All output, producing a smooth CV; the degree of slewing varies with clock speed.1115 |
| Gate I | gate | 0V to 8V | Gate output for bit 0 of the shift register; 8V gate with 50% duty cycle of the clock.1115 |
| Gate II | gate | 0V to 8V | Gate output for bit 1 of the shift register; 8V gate with 50% duty cycle of the clock.1115 |
| Gate III | gate | 0V to 8V | Gate output for bit 2 of the shift register; 8V gate with 50% duty cycle of the clock.1115 |
| Gate IV | gate | 0V to 8V | Gate output for bit 3 of the shift register; 8V gate with 50% duty cycle of the clock.1115 |
| Gate V | gate | 0V to 8V | Gate output for bit 4 of the shift register; 8V gate with 50% duty cycle of the clock.1115 |
| Gate VI | gate | 0V to 8V | Gate output for bit 5 of the shift register; 8V gate with 50% duty cycle of the clock.1115 |
| Gate VII | gate | 0V to 8V | Gate output for bit 6 of the shift register; 8V gate with 50% duty cycle of the clock.1115 |
| Gate VIII | gate | 0V to 8V | Gate output for bit 7 of the shift register; 8V gate with 50% duty cycle of the clock.1115 |
