Befaco Lich

Programmable DSP module on Rebel Tech's OWL platform with stereo I/O and CV.

12 HP Eurorack module

Lich is a 12HP programmable multi-function module built on Rebel Technology's OWL DSP platform, a collaboration between Befaco and Martin Klang. Four pots (A/B/C/D), two push buttons and a rotary encoder give physical control over user-loadable patches; CV inputs with attenuators sum into each pot for full voltage control. A USB Type B device port lets you upload patches written in Pure Data, C++, FAUST or Max Gen from rebeltech.org/patch-library, while a USB Type A host port hosts MIDI controllers. Stereo audio I/O, two gate inputs, two CV outputs and a gate output round out a panel that can become a reverb, stereo delay, harmonic oscillator, MIDI/CV bridge or anything you code yourself. The 7-segment display shows the active patch number and provides loading feedback.

How-To Guides

  • Boot Lich and load a different patch
  • Lush Silky Reverb on a stereo bus
  • Tap-tempo stereo delay synced to a clock
  • Harmonic Lich as a CV/MIDI oscillator
  • MIDI controller → CV with the MIDI Modular patch
  • Upload a custom patch over USB
