Meet the Demon Box: The Instrument That Channels the Unknown

video uploads by Eternal Research

"The Demon Box is more than an instrument. It’s a portal where DMX, MIDI, Eurorack, and built-in lighting converge, transforming hidden energy into real-time sound, light, and motion.

You’ve seen what the Demon Box can do, now it’s time to go deeper.This video shows how to unlock its full potential, bending these forces into a single living entity you can shape, route, and command."

Eternal Research Demon Box
Summon the sounds of electromagnetic oddities with Demon Box from Eternal Research, an innovative instrument that condenses the practice of using EMF for audio and control signals in a unified device. At the top surface of the Demon Box's triangular enclosure, a literal platform for audio experimentation awaits. Here, three channels of EMF inductor pickups are arranged in a nested spiral formation, which can be used to create unique tones and control signals by interacting with any object that produces EMF near the inductors. Power tools, FM radios, eBows, tuning forks, and other personal electronics become diverse sources for synthesizing tones, controlling modular synths, and even producing MIDI signals. Turning the inaudible waves of ambient and ubiquitous electro-ephemera into creative signal sources, the Demon Box offers a deep well of musical meaning-making waiting to be discovered.

For each of the three channels in Demon Box, the front panel offers control over gain staging and signal routing. Using a switch for each channel, you can select input sources for the inductors, an external signal from the three 1/4" audio inputs, or a mix of both with the Admix balance control. You can also set any of the channels to be totally silent with this switch for a simpler set-up. Each channel's mix of inductor and/or external signals is sent to dedicated individual outputs, and there is also a summed output onboard that mixes each channel evenly. The amplitude of these channels are used to create both CV and MIDI control signals. Independent CV outputs for each channel offer +/-5V range of control for interacting with modular synths and other CV capable gear. The 5-Pin MIDI or USB-C output offers three channels of note data on MIDI channels one through three, and another three channels of CC signals, with CC1, CC2, and CC3 offering chaotic, medium, or smooth interpolation for each of MIDI channels four through six. Using these control signals, you can apply the Demon Box's unique methodology of experimental signal generation to control other instruments, video synthesizers, DMX lights, and anything else capable of interacting with CV or MIDI signals.

While the core concepts underlying the Demon Box's captivating capabilities are age-old practices in experimental electronic sound, its design provides a comprehensive and intuitive tool for exploring creative applications from a long lineage of signal-sleuthing artistry. Whether you're a dedicated audio experimentalist, a visual or installation artist working with electronics, or just want to know what songs your electric toothbrush ca
