Analog Paraphonic Synthesizer V2

The EREBUS is an analog synthesizer with various patching options. It's 100% analog (except for the Midi interface and a part of the delay effect) and 100% handmade, only with Through Hole components. It's a versatile synth machine, capable of producing some huge bass sounds, piercing leads and great ambience! Advanced synthesis knowledge is required to successfully use the EREBUS.


  • Analog 2-voice Paraphony or Unison sounds, only with Through Hole components
  • 2 x VCO with separate glide controls
  • 2 pole (12dB/ocv) pre-fed resonating VC Low Pass Filter
  • VC LFO with additional VC Depth
  • 2 x Envelope Generators (1xADSR and 1xAR dedicated to the AMP)
  • VC Delay/Echo
  • 15 patches for an astonishing Modular experience
  • CV Outputs: LFO, Envelope (attenuated), Modulation Wheel (attenuated), Gate, Osc1 pitch (1V/ocv), Osc2 pitch (1V/ocv)
  • CV Inputs: Osc1, Osc2, Echo time, VCF, CV, GATE, LFO rate, PW , VCA
  • Paraphony CV/GATE outputs allows you to turn monophonic devices into Paraphonic, or even combine 2 monosynths into a paraphony orgy.


  • Work with 15VDC 1A power supply.
  • MIDI interface: Midi in/through DIN socket, Pitch note/gate on-off, retrigger function (on-board), Mod wheel (patched on-board), Pitch wheel, MIDI Channel select 1-7 or Omni (DIP switch)

  • Gate out: 0-5V
  • Osc1, Osc2, CV IN: works at 1V/oct and can accept from +/-12V
  • CV1, CV2 outs: send 1V/oct (converted to analog via midi keyboard)
  • Mod Wheel out: converts the midi modulation wheel to analog 0-5V out
  • Envelope out: 0-6.6V depending on the depth setting
  • LFO out: +/-5V
  • LFO frequency range: 0.009Hz (110sec) up to 30Hz (0.033sec)
