Distortion with feedback loop and interchangeable rectification diodes

Miasma is a voltage controlled distortion with a feedback loop you can push to self oscillation for insane results and interchangeable rectification diodes, giving you an unlimited amount of sound possibilities within one module.

Miasma's feedback path feeds the distorted signal back in the input with no phase inversion, causing the module to self oscillate, even with no input. The feedback path can be opened to send it through different effects making Miasma perfect for complex feedback patches.

A blend knob allows Miasma to be use in a precise way, for more complex sound design.

The module’s clipping diodes are mounted on a header making it easy to change them and craft the sound you want. There module ships with six different diodes, from germanium to LEDs and you can experiment adding your own. The output level may vary depending on which diodes you use, this can be adjusted with the level trimmer on the front panel.


  • Gain control up to +20dB
  • Feedback VCA
  • Blend control between dry and wet signal
  • Attenuverters on Gain and Feedback CV
  • Level trimmer to adjust the output volume

Technical characteristics

  • OTA based VCAs for gain and feedback control
  • Feedback output jack is normalized to the feedback input jack
  • One rectification diode per waveform polarity, making it possible for symmetrical or asymmetrical distortion
  • Diodes can be swapped in and out without the need of tools

Handbuilt in Paris, France
