What began as Erica Synths’ attempt to complement the rest of Hexinverter’s offering with a Eurorack snare synthesis module quickly evolved into an all-analog, multi-instrumental module with power that extends far beyond its dual-voice, drum-sound core. Enter, the Mutant Machine, brought back to life with unerring accuracy via Erica Synths. This 29HP percussion synthesis engine channels the spirit of the lauded 909’s musicality, remixed and reimagined to elicit club-worthy and alien sounds befitting dancefloors throughout the galaxy. Its comprehensive array of CV, Gate, and audio I/O points allow for near-endless intra-modular exploration and tone-crafting, extending its sonic profile beyond percussive possibilities to include all manners of timbral shaping and even functionality as a complex VCO! Plus, given there are no microcontrollers, each signal and waveform is generated by discrete components and ICs, exciting Sweetwater’s synthesists with the limitless applications of its distinctive sonic characteristics with their Eurorack rigs.

Multimode sound design for rhythm and beyond





The Mutant Machine centers around two voices: Membrane and Snappy. Together, they allow you to craft nuanced drum sounds by dividing the tonal and timbral elements. Membrane comprises a pair of Hexinverter’s voltaic Inverter Core oscillators, each offering a trio of waveforms and flexible voicing options that can be individually adjusted and controlled manually or via CV. On the opposing end of the module, Snappy deploys a dedicated noise oscillator for snare-like textures with modulatable elements like Click, Decay, Pitch, and more. Each half of this drum-sound dyad boasts individualized external audio inputs to replace onboard sources while expanding the module’s interoperative and aesthetic capabilities. Similarly, dedicated Wave and Noise outputs extend sonic possibilities to include utilizing the module as a complex VCO with other modules in your setup. Its central sound-shaping parameters include the cutting-edge Wavescanner, augmenting sonic depth by introducing a form of timbral control for its complex oscillations. Plus, its 20 I/O points for CV, Gate, and audio signals mean that nearly every parameter is voltage-controllable, and its aural machinations can be utilized with limitless external audio, culminating in a musical machine with maximum integration possibilities.
