Intellijel Designs Korgasmatron 2


The Korgasmatron is a dual clone of Korg´s MS-20 filter. It's sound can range from ultra clean and precise, to extremely ballsy and dirty.The resonance is incredibly musical and interesting and is prime for all sorts of experimenting and sound design. The normalling, routing and cv options have been carefully selected to allow for a lot of control over the modules functionality and capabilities.

The new version Korgasmatron 2 has more filter types, overdrive, enhanced crossfading and a header for an expander module.



The Korgasmatron is two independent filters, each with six switchable modes:

  1. LowPass 1-pole (6dB)
  2. LowPass 2-pole (12dB)
  3. BandPass 1-pole (6dB)
  4. HighPass 2-pole (12dB)
  5. HighPass 1-pole (6dB)
  6. Band Reject (notch) 1-pole, 6dB; different sound than notch on Corgasmatron 1

A Switch links the two filters allowing both parallel and serial routing via normals to input B (which can be broken by inserting a cable at input B). Oscillates very easily and can be used as a dual sine VCO with a tracking of almost 4 octaves. Using the unique resonant drive controls (Q drive) this Sine shape can be colored. In addition you can clip the adio signals on the inputs. Jumpers on the back to select "modern" or "vintage" resonant modes (two different feedback paths for the resonance that use different diodes)

Built in full featured cross fader allows voltage controlled xfading between the two filters. There is a switch to select crossfading direction.The Korgasmatron 2 has the crossfader circuit of the uFade, now with an dedicated attenuator for the crossfading CV.

The new version 2 has expansion jacks for adding additional filter inputs and VC control of resonance

The original circuit was designed by analog guru David G. Dixon after carefully studying and analyzing the classic Korg MS-20 filter. His work resulted in a completely original circuit based around SSM2164 VCA chips. His design was capable of almost identical results but was far more versatile. This is not a part for part clone, it is an entirely new and modern circuit with many enhancements.


Crossfader CV input, audio mix output
Each filter has an audio input, an audio output, 3xCV inputs for cutoff (one of them is fixed to 1V/oct, two have attenuators)
