Dreadbox Lil' Erebus Complete Voice Eurorack Synthesizer Module (Assembled)

Dreadbox Lil' Erebus is a slightly simplified eurorack modular version of the well-known and highly-regarded Erebus desktop synthesizer. It has a new, simplified interface with sliders replacing most of the knobs found on the desktop version.

Lil' Erebus has a simple MIDI-to-CV converter that will convert MIDI notes to CV values and MIDI note on messages to gates. Lil' Erebus can be played over MIDI either monophonically or duophonically. Up to two Lil' Erebus modules can be polychained together.
