The Field Kit is one of those rare instruments that doesn't fit neatly into any single category, which is exactly why it's become a favorite among sound designers, field recordists, and experimental musicians who refuse to be confined by traditional synthesis. Rather than chasing the latest oscillator count or filter topology, Koma Elektronik built something that treats the entire world as your sound source.
At its core, the Field Kit is a four-channel mixer optimized for the kind of signals most gear struggles with—microphones, contact microphones, electromagnetic pickups, and anything else you can patch into it. Each channel gets individual gain, mix level, and tone controls with both low-pass and high-pass filtering. Beyond the mixer, you get a CV-controllable AM/FM/SW radio receiver that can be swept across frequencies using control voltage, an envelope follower that converts incoming audio into CV and gate signals, and a low-frequency oscillator with selectable square, triangle, or mixed waveforms. The DC interface outputs 9V at up to 500mA, letting you drive motors, solenoids, and LEDs directly from the unit. There's also a signal interface that converts switch inputs and sensor data into gate and CV signals with adjustable trigger lengths from 1ms to 1 second. Everything is housed in a compact wooden case measuring 20 by 13 by 5.2 centimeters, with a power supply included.
The Field Kit has found genuine appreciation among musicians working at the intersection of acoustic and electronic sound. People gravitate toward it specifically because it's built to handle real-world signals and unconventional sound sources rather than forcing you into a modular mindset. The radio tuner alone opens up possibilities most synthesizers never touch, and the sensor interface transforms the instrument into something that responds to physical interaction and environmental input. It's become a go-to tool for anyone building hybrid rigs or exploring generative and interactive sound design.
