øchd expander

Overview

The Instruō øchd expander [ø]4^2 is a powerful expansion module that transforms your beloved øchd modulation source into a modulation powerhouse. Originally launched in 2019 in collaboration with Ben "DivKid" Wilson, the øchd has become a staple in thousands of Eurorack systems. This expander takes the original 8 LFOs and adds 16 additional outputs with 4 new sets of functionality, giving you 24 modulation sources in just 8HP total when combined with the original øchd module.

Using øchd's LFOs as signal sources, the expander generates full wave rectified unipolar positive LFOs, analog diode logic operations, cascaded stochastic triggers, and R-2R 4-bit random voltage sources - all controlled by øchd's single frequency control and CV attenuverter.

Features

• 16 additional outputs expanding øchd's modulation capabilities
• Full wave rectified unipolar positive LFOs for always-positive modulation
• Analog diode logic for minimum and maximum voltage mixing
• Cascaded stochastic trigger signals for complex rhythmic patterns
• R-2R 4-bit random voltage sources for chaotic and wild modulation
• Single frequency control - all functions controlled by øchd's frequency knob and CV
• Compact design - adds only 4HP to your øchd setup
