Granular processor

In 2019 the launch of the arbhar heralded a new generation of granular processing in Eurorack. Sampled audio could be chopped into tiny grains, scattered, shaped, re-pitched, reversed, and layered for an endless range of audio manipulation ranging from seamless frozen tones to mutated acousmatic madness. Each grain sounds with its defined specifications. When modulation is used, the “per-grain parameter” definition allows for true polyphonic layering.

With the introduction of firmware version 2 (2023) comes a complete rewrite of the entire codebase to implement both technical and conceptual improvements that will enhance the entire user experience of arbhar. We have ensured that the overall feel of the module has been preserved as much as possible. Advances in efficiency and expanded features will allow arbhar to explore many more sonic and musical spaces.
