After Later Audio Benjolin V2
Self-patching chaos oscillator with built-in Rungler
20 HP Eurorack module
The Benjolin V2 is a chaotic Eurorack synthesizer featuring two oscillators, a Rungler stepped CV generator, and a multimode filter. The oscillators feed data and clock into a shift register whose R2R DAC output can be mixed back into the oscillators, creating a self-referential chaotic system constantly seeking balance. It is a generative, unpredictable instrument capable of evolving textures, chaotic melodies, and experimental noise.
