Noise Generator
noise-generatorProduces white noise and colored noise (mixable red/low-frequency and blue/high-frequency components). Noise generated 100% analog by amplification of transistor noise. [34] -
Random Voltage Generator
random-voltage-generatorProduces random voltage derived from colored noise signal by lowpass filtering; rate and amplitude are controllable. [34]

Outputs (3)
| Name | Signal | Voltage | Description |
|---|---|---|---|
Colored |
audio | — | Colored noise output whose spectrum is determined by the Blue and Red controls [34] |
Random Output |
cv | — | Random voltage output whose rate of change and amplitude are determined by the Rate and Level controls [34] |
White |
audio | — | White noise output [34] |
Parameters (5)
| Name | Type | Range | Min FW | Behavior |
|---|---|---|---|---|
Blue |
knob | — | — | Controls the amount of blue noise (high frequency components) in the colored noise output [34] |
Level |
knob | — | — | Controls the amplitude of the random voltage output [34] |
Random Control |
menu_setting | — | — | Two LEDs indicating whether the random voltage is positive or negative; relative brightness also shows amplitude [34] |
Rate |
knob | 0 – 10 | — | Controls the cycle time T of the random voltage output. Setting of 0 means fast voltage changes; setting of 10 means slow changes. [34] |
Red |
knob | — | — | Controls the amount of red noise (low frequency components) in the colored noise output [34] |
