The electromagnetic activity already present becomes the raw material.
Beneath the surface of every powered room lies an invisible electromagnetic chorus — and Eternal Research has built an instrument that finally listens. At Superbooth 2026 in Berlin, the Los Angeles studio debuts the Demon Box, a production-ready device that captures ambient EMF signals from surrounding electronics and converts them into playable audio, CV, and MIDI. Rather than generating sound from within, it draws from the electromagnetic life already present in any space, inviting musicians to compose with the invisible architecture of the world around them.
- Every powered device in a room emits electromagnetic fields that have always been there, unheard — the Demon Box finally makes them audible and playable.
- Because no two electromagnetic environments are identical, the instrument is fundamentally unpredictable, producing different sonic material in Berlin than in Los Angeles, in a studio than on a stage.
- Eternal Research will run live demonstrations at Booth Z065 across all three days of Superbooth's tenth anniversary, letting visitors experience the instrument firsthand rather than take anyone's word for it.
- The device outputs audio, control voltage, and MIDI simultaneously, meaning it slots into existing setups and gives musicians real-time sculptural control over whatever electromagnetic landscape surrounds them.
Walk into any room and you're already inside an electromagnetic field — the hum of lights, the buzz of cables, the invisible activity thrown off by every powered device nearby. Eternal Research, a creative technology studio with roots in Brooklyn and a base in Los Angeles, has spent years learning to listen to that hidden layer, and the result is the Demon Box.
Debuting at Superbooth 2026 in Berlin as a finished, production-ready instrument, the Demon Box captures ambient EMF signals from the surrounding environment and converts them into audio, control voltage, and MIDI data. There is no oscillator generating a tone from scratch, no sample library to browse — only the electromagnetic energy already present in the room, shaped in real time by whoever is playing.
The instrument's defining quality is its environmental dependency. A studio in Berlin yields different material than one in Los Angeles. A nearby laptop, a lighting rig, or a stray power cable each shifts what the device has to work with. Players become sculptors of invisible forces, responsive to a landscape that changes moment to moment and place to place.
Co-founder Alexandra Fierra has described Superbooth as the right venue for exactly this kind of exchange — a place where sonic ideas find their audience. The team will occupy Booth Z065 in the ZW Tents area for all three days of the festival, running demonstrations and staying available for direct conversation. The tenth anniversary edition of Superbooth, one of Europe's most significant gatherings for synthesizer culture, offers an ideal setting for an instrument that resists description and rewards hands-on encounter.
Walk into any room and you're surrounded by invisible noise—the electromagnetic hum of lights, the buzz of cables, the ambient field thrown off by every powered device within reach. Eternal Research, a creative technology studio based in Los Angeles with roots in Brooklyn, has built an instrument that listens to that invisible world and turns it into music.
The Demon Box, arriving at Superbooth 2026 in Berlin as a finished product, does something most synthesizers don't: it captures the electromagnetic fields already present in your environment and converts them into raw, workable sound. No oscillator generating a tone from scratch. No sample library to choose from. Instead, the device picks up the ambient EMF signals surrounding it—the electromagnetic activity that's always there, humming beneath notice—and transforms that energy into audio, control voltage, and MIDI data that a musician can shape and manipulate in real time.
What makes this approach compelling is its unpredictability. Because the electromagnetic environment changes from room to room, from moment to moment, the Demon Box never sounds quite the same twice. A studio in Berlin will yield different sonic material than one in Los Angeles. The presence of a laptop, a lighting rig, or a nearby power cable shifts what the instrument has to work with. Players become sculptors of invisible forces, tactile and responsive, working with whatever electromagnetic landscape surrounds them rather than summoning sound from a predetermined palette.
Alexandra Fierra, co-founder of Eternal Research, framed the philosophy plainly: Superbooth is where sonic ideas get shared and new visions take shape. The studio will occupy Booth Z065 in the ZW Tents area across all three days of the festival, running live demonstrations and making the team available for direct conversation. Visitors will be able to sit with the instrument, feel how it responds, understand through experience rather than explanation what it means to play an environment.
Superbooth itself is marking its tenth anniversary this year, and it remains one of Europe's most significant gathering points for synthesizer culture and electronic music broadly. The festival's mix of indoor exhibits and outdoor installations creates an ideal setting for an instrument like the Demon Box—something that demands to be experienced, that resists description and requires hands-on encounter. The team behind it will be there to walk visitors through the development process and the thinking that shaped the device, but the real conversation will happen when someone sits down and tries to make music from the electromagnetic fields in the room.

La Conversación del Hearth Otra perspectiva de la historia
So the Demon Box is essentially listening to the electromagnetic noise that's already in the room?
Exactly. It's not generating sound from scratch. It's capturing the ambient EMF that's always present—from lights, electronics, cables, all of it—and converting that into something playable.
That means the same instrument sounds different in every space?
Completely different. The electromagnetic environment is never the same twice. A room in Berlin will have a different signature than one in Los Angeles. Even moving the instrument a few feet can shift what it picks up.
Isn't that a limitation? How do you perform with something so unpredictable?
That's the point. It's not a limitation—it's the creative material. You're not fighting against a fixed oscillator or sample bank. You're working with what the environment gives you, shaping it in real time. It's tactile in a way traditional synthesis isn't.
Why bring it to Superbooth specifically?
Because Superbooth is where people come to explore sonic ideas. It's a place where curiosity drives everything. An instrument like this needs to be felt, not explained. You have to sit with it to understand what it does.
What does the team hope people take away from seeing it?
That sound doesn't have to come from a preset or a sample. It's already around you. The Demon Box just makes that visible—or audible, rather.
