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.
