Wogglebug
Random voltage generator originally designed by Grant Richter of Wiard Synthesizers. An evolution of the Buchla Model 265 Source of Uncertainty lineage, generating correlated stepped, smooth, and woggle CVs plus two audio-rate VCOs, a ring-mod output, a burst gate output, and a clock output — all from one internal chaotic core.727
Capabilities 5
- Clock Sourceclock-source
- Internal voltage-controlled clock with range from 1 minute per cycle to ~200Hz; outputs a master clock signal independently of S&H clocking.727
- Random Sourcerandom-source
- 727
- Random Voltage Sourcerandom-voltage-source
- Generates correlated stepped, smooth, and woggle random CVs from a single internal chaotic core, with all outputs simultaneously available.727
- Ring Modulatorring-modulator
- Digital ring modulation of Smooth VCO and Woggle VCO with optional Influence input signal; produces pulse-wave audio output.727

| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (1) | |||
| Influence Input | mixed | 0V to 10V | CV and/or Audio Signal input; modulates frequency of Smooth and Woggle VCOs, feeds the Ring-Mod circuit, and level-shifts the Woggle CV signal.727 |
| Outputs (8) | |||
| Burst Output | gate | 0V to 10V | Square random gate signal synced to the clock and influenced by Stepped, Smooth, and Woggle controls.727 |
| Clock Output | clock | — | Square clock signal from the internal clock generator; always runs at the set rate regardless of external clocking or Disturb button activity.727 |
| Ring-Mod Output | audio | — | Pulse wave audio-rate signal; ring-modulated product of Smooth VCO, Woggle VCO, and audio-rate signal at the Influence Input (if present).727 |
| Smooth CV Output | cv | 0V to 10V | Smooth random control voltage; smoothness set by the Speed/Chaos control.727 |
| Smooth VCO Output | audio | — | Shark's Fin (Sharktooth) wave audio-rate signal; controlled by Ego Input, Ego/Id Balance, Influence CV Input, and Speed/Chaos controls.727 |
| Stepped Output | cv | — | Stepped random voltage; new value at each clock pulse. At audio clock rates with audio at Ego Input, produces bit-reduction effects.727 |
| Woggle CV Output | cv | 0V to 10V | Derived from the Smooth/Stepped CV; quivers and chases the core system, smoothed by the Woggle panel control. Stepped voltages with decaying sinusoids at the edges.727 |
| Woggle VCO Output | audio | — | Square wave audio-rate signal; controlled by Woggle panel control, Ego Input, Ego/Id Balance Control, Influence CV Input, and Clock Rate/Chaos controls.727 |
Parameters 3
| Name | Type | Range | Behavior |
|---|---|---|---|
| Disturb Button | button | — | Direct control of the Sample and Hold circuit: pressing triggers a sample; holding pauses/holds the CV outputs. Can slow a fast-running system or kick-start a slow one.727 |
| Speed/Chaos | knob | 0.0167Hz – 40Hz | Dual-purpose control: sets the rate of the internal clock generator and the lag processor feeding the Smooth CV circuit. CCW slows and smoothes; CW quickens and makes Smooth CV jittery.727 |
| Woggle Control | knob | — | Sets how quickly the Woggle circuit tracks the Smooth/Stepped circuit. CW slows the Woggle CV; CCW speeds it up.727 |
