Notes: Brilliant experimental box inspired by electroacoustic musicians including John Cage. Signal processing, mixing, sound generation and the ability to send voltages to physical devices like motors and buzzers. Super creative.

Supplier's notes:
The new KOMA Elektronik Field Kit is the perfect tool for everyone who would like to experiment with electro acoustic sound. Use everyday objects, amplify them and use them to make sound, like our heroes John Cage and David Tudor used to do!

The Field Kit is optimized to process signals from microphones, contact microphones, electromagnetic pickups and able to run DC motors and solenoids. On top of that it can receive radio signals and convert signals from switches and sensors into control voltage!

Let's get more detailed...

The Field Kit boasts 7 separate functional blocks all focussed on receiving or generating all types of signals. They are designed to operate together as a coherent electroacoustic workstation or alternatively together with other pieces of music electronics with the ability to use control voltage signals.

The Four Channel Mixer is the beating heart of the Field Kit, providing a fully functional mixer with individual Gain, Mix Level and Tone control over each channel and individual Master- and Aux sub-mixes.

The level of the Master and Aux Channels can be set with the Master Volume and Aux Volume controls and the channels being sent to the Aux sub-mix can be set with dedicated Aux Select-buttons. The Aux sub-mix is pre-fader.

The CV Radio is a CV-controllable radio receiver capable of receiving radio frequencies on AM/FM and SW bands. Additionally it provides the ability to catch electromagnetic waves for further processing inside the Field Kit. The frequency of the radio can be set with a dedicated multifunctional Search-control which acts both as a manual CV-source and as an input attenuator for a CV-signal.

The Envelope Follower in the Field Kit applies two functions to the waveform you send to the input: full-wave rectification (mirroring of negative portions of the waveform) and low-pass filtering (averaging). It can also be used for frequency doubling of a signal, which is a great tool to have in the electroacoustic domain.

The Low Frequency Oscillator generates periodically varying voltages to be used as control signals. The output waveform can be set with a three-position Waveform-control and gives out either a Square-, Triangle- or a mix of Square and Triangle waveforms.

A very cool function of the Field Kit is the DC Interface. You can use its output voltages to run little motors, fans, solenoids, buzzers and control them with control voltage signals. You can pick up the vibrations and electromagnetic waves with the contact microphones and electromagnetic pickup.

The Signal Interface is a nifty toolset to transform the raw signals of a wide variety of sensors and switches into signals that can be used with the Field Kit or other gear. This means you can trigger or control sound by light, heat, humidity, distance, speed, acceleration, proximity, pressure, force, level, all depending on what type of switch or sensor you are using! Ideal for sound installations!

Notes: The Chromaplane is an instrument created in collaboration between KOMA Elektronik & Passepartout Duo.

The Chromaplane is played using two electromagnetic pickup coils, that are moved over its surface to listen to a cloud of electromagnetic fields produced by the instrument.These ten fields are represented by small indicators on the instrument's surface.

The Chromaplane is fully polyphonic, meaning that all ten of the instrument's analogue square wave oscillators are always sounding - this makes the instrument ideal for both sculpting complex drones, and playing agile melodies. Each field can be tuned using its corresponding adjustment screw. The oscillators are additionally organized into three rows, each with a switch that drops that row's pitch one octave.

The timbre of the Chromaplane can be further shaped using its internal VCF, a 4-pole low pass filter that darkens the instrument's sound and is also modulated by the internal audio signal, allowing for rich harmonic sounds and timbres reminiscent of frequency modulation. A lo-fi delay/echo effect with CV controlled time adds a sense of ambiance and rhythmicity to the dry signal's output.

The Chromaplane also features an external audio input, allowing the player to route other sounds to one electromagnetic field on the instrument's surface. The instrument's envelope output can also be used to modulate parameters on the instrument, or on other hardware synthesizers.

The Chromaplane includes: The Chromaplane itself, 2 pickup coils, 1 tuning screwdriver, 1 power adapter that works worldwide, 1 manual
