Eternal Research launched a successfully funded Kickstarter campaign back in September, but this was the first time I was able to see the Demon Box in person. Think of it like a supercharged version of the Soma Labs Ether featured in a handful of our gift guides. The Demon Box doesn’t make any sound on its own, instead it features three pickups that turn EMFs (electromagnetic fields) into music — or at least audible noise. Run a cellphone, power drill or a tuning fork across the top and you’ll get unique whines, hisses, clicks and beeps that only that device could produce. But where the Ether is basically just a microphone, the Demon Box is an instrument designed for live interaction and controlling other devices. In addition to outputting audio, it can also convert those electro magnetic fields into CV (control voltage) for controlling eurorack synths or MIDI for triggering a visual synthesizer, or all three simultaneously. There are tons of options out there if you want a buzzy sawtooth bass, but if you want to turn the invisible radiation emitted by a TV remote into a centerpiece of a multimedia performance, this is basically your only option.
