The Moffenzeef Modular Genetically Modified oscillator (GMO) is an open source, lo-fi, digital, esoteric drum module. Rather than taking a “set it and forget it” approach to drum synthesis, the GMO is outfit with complete bipolar CV control over every parameter. The user can dial in everything from microsound blips, to drawn out gongs, to screeching mutated beasts. When in looping mode the GMO can be viewed as a mutated VCO, combining the best elements of granular and wavetable synthesis. Its low resolution output means lots of side-band modulation, noise, and most importantly: character. This beast is best understood in practice rather than in theory.


  • “SPECIMEN” hot swaps sample selection
  • “SPEED” controls pitch of sample (0.01% - 300%),
  • “HEAD” controls start of sample selection
  • “TAIL” controls end of sample selection
  • “BANG!” input resets sample to start time
  • "OUROBOROS" toggles looping on and off
  • "OUROBOROS" input toggles looping on and off with a clock or gate
  • Bipolar CV control over all parameters
  • Reverse polarity protection, power filtering, and keyed headers
  • Proper +5/-5 CV input buffering and current limiting
  • Selection window can be as small as 10 samples
  • Samples held in flash memory
  • 12 bit audio output
  • Skiff friendly - low power, shallow mounting depth
