A new MCO Firmware v106 is now available! Here we make a few patches to demonstrate the new additions. New features include CV control over user presets, random preset generation, a multimode filter added to the DigiWave voice and selectable functions for the A and B buttons of the AXON-2 expander.
The MCO (mkII) is a highly versatile digital VCO and voice module inspired by 90s/00s digital synths shrunk into just 6HP. It offers a broad collection of unique, high-quality synth voices, each with extensive, customizable parameters.
