When JoMoX first introduced the Resonator Neuronium in 2004, they weren't trying to build another subtractive synth—they were creating an analog neural network that could generate evolving, living soundscapes that shift and mutate on their own. It's the kind of machine that makes you rethink what a synthesizer can be.
The heart of the Neuronium is its six interconnected analog resonant neurons that feed back into each other in ways you can control and reprogram. Each neuron acts as a resonant filter, and you can route their outputs positively or negatively through a hexagonal control layout on the left side of the unit, letting you shape the feedback network however you want. The machine includes FM modulation for each voice, analog envelope generators, MIDI control via 5-pin DIN, velocity and aftertouch sensitivity, and an internal sequencer that can store and recall up to 101 patches. Audio comes in and out via stereo connections, and the whole thing sits in a distinctive blue-coated iron chassis that's become iconic in experimental synth circles.
What makes the Neuronium genuinely different is that it doesn't try to emulate classic synthesis—it's built around the idea of creating interactive, self-evolving systems where the six resonators bounce off each other in unpredictable but musical ways. Players who've spent time with it describe discovering sounds that seem to have their own life, shifting and transforming every few minutes without external input. It's not a machine for everyone, and it demands patience and experimentation, but for sound designers and electronic musicians looking to break away from conventional approaches, it remains one of the most intriguing experimental instruments ever made. The 2004 original run was extremely limited, and a reissue in 2019 brought only 50 units back into circulation, making it a rare find in the used market today.
