Erica Synths shared this video demo of their version of the Hexinverter Électronique Mutant Machine percussion module for Eurorack systems.

The Hexinverter Électronique Mutant Machine began as a quest to create a rich-sounding Eurorack snare drum synthesis module to complement the existing Mutant Drums. The project quickly became too large and costly to justify the module being capable only of snare drum sounds. So, the decision was made to learn from the architecture of the TR-909’s snare and kick circuits, and to develop a module capable of generating multiple forms of analog percussion, and various other effects.

The Machine has its roots in classic analog percussion synthesis. The signals and waveforms are all generated by discrete components and ICs.

Hexinverter Électronique announced in 2022 that it would be shutting down, because global supply chain issues had made it impossible for them to manufacture and sell enough modules to be viable. Since then, Erica Synths has announced a collaboration with them to make Hexinverter designs available again.

Redesigned by Erica Synths, in collaboration with Hexinverter Electronique, the module features a manual trigger button.

The Erica Synths Hexinverter Électronique Mutant Machine is available now for € 320.00.
