Make Noise Wogglebug

Your synthesizer's ID monster — woggle everything

10 HP Eurorack module

The Make Noise Richter Wogglebug is a complex random voltage and audio generation system inspired by Grant Richter's original Wogglebug design and the Buchla 265 Source of Uncertainty. It combines a voltage-controlled clock, sample and hold, two lag processors, a random gate burst generator, and two VCOs with digital ring modulation into a single interconnected system. Its musical character is unpredictable and alive — capable of gentle probabilistic CV wandering, chaotic audio noise textures, and everything in between.

Features

  • Voltage-controlled internal clock generator from 1 minute per cycle up to ~40Hz (extended to ~200Hz with Speed CV)
  • Sample and Hold with Ego Input for direct signal injection at the heart of the system
  • Ego/Id Balance Control for setting range of probable values or balancing external/internal signal sources
  • Stepped Random Voltage Output with activity window LED
  • Smooth CV Output via lag processor controlled by Speed/Chaos
  • Woggle CV Output — stepped voltages with decaying sinusoids at edges, chasing the Smooth/Stepped circuit
  • Woggle Control sets how quickly the Woggle circuit follows the Smooth/Stepped circuit
  • Smooth VCO with Sharktooth (Shark's Fin) waveform at audio rate, 10Vpp
  • Woggle VCO with Square wave at audio rate, 10Vpp
  • Digital Ring-Mod Output combining Smooth VCO, Woggle VCO, and Influence Input signal
  • Influence Input modulates frequency of both VCOs, feeds Ring-Mod, and level-shifts Woggle CV
  • Random Gate Burst Output synced to clock, influenced by Stepped, Smooth, and Woggle circuits
