Koma Elektronik Field Kit FX

Now optimized for eurorack, Field Kit FX is ideal for use with Koma Elektronik's Field Kit electroacoustic workstation, but will work smashingly in any eurorack or modular environment. It features an array of useful effects that correspond with many of the strengths of the original Field Kit, but can be meaningfully integrated into a variety of setups. It is comprised of seven "blocks", including a Looper, Frequency Shifter, Sample Rate Reducer, Digital Delay, Analog Spring Reverb, 4-channel VCA Mixer, 4-step Sequencer, and Envelope Generator. All of these can be combined and routed through the unit's 4-channel CV Interface, giving users all the tools they need to exercise precise control over their patch.

Koma Field Kit FX & Field Kit Played With A Giant Wrench
The Koma Field Kit & Field Kit FX are a fun set of tools and effects for electro-acoustic music including contact mic pre-amps, mixers, frequency shifter, delay and spring reverb, voltage controlled radio and a few other handy utilities.
