KOMA Elektronik Chromaplane

The Chromaplane was 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. The instrument is fully analog and polyphonic, this makes the instrument ideal for both sculpting complex drones, and playing agile melodies.

There is a 4-pole low pass filter that darkens the instrument’s sound, and a lo-fi delay/echo effect for space and ambiance.

Each field can be tuned using its corresponding adjustment screw. A special physical tuner with a complimentary Chromaplane tuning website allows you to explore a curated library of tunings, and save and share their own too.
