Meet the Instruō øchd expander ([ø]4^2), an expansion module for one of Eurorack’s most beloved modulation sources, øchd.
Launched in 2019 and designed in collaboration with Ben “DivKid” Wilson, the Instruō øchd has set a standard for compact and versatile modulation sources which can now be seen across thousands of eurorack systems. The Instruō øchd expander [ø]4^2 adds 16 outputs and 4 new sets of functionality to øchd’s normal operation.
Using øchd’s LFOs as signal sources, øchd expander [ø]4^2 adds full wave rectified unipolar positive LFOs, analog diode logic for minimum and maximum voltage mixing, cascaded stochastic trigger signals for interesting rhythmic patterns, and R-2R 4-bit random voltage sources for all things wild and chaotic – all of which are controlled by øchd’s single frequency control and CV attenuverter.
Designed in collaboration with Ben "DivKid" Wilson, the Instruo øchd packs 8 all analogue LFOs into a convenient 4HP package. Each independent core is free running with rates configured from fastest to slowest arranged from top to bottom, with a wide frequency range and CV-controllable global rate with attenuverter.
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.
