Instruments for daydreaming

Created by KOMA Elektronik and Passepartout Duo

The Chromaplane and Haloplane are unique electromagnetic synthesizers played using pickups. They’re instruments that emphasizes expression, intuition, and play.

Chromaplane

Fully analog synthesizer with ten tunable fields

Self-contained and pure, the Chromaplane creates a cloud of electromagnetic oscillations above its surface - play melodies by drawing above the surface, or just drone. A simple and intuitive interface focusing on immediate and organic electronic sound.

  • expressive electromagnetic playing surface

  • ten tunable analog oscillators

  • resonant voltage controlled low pass filter

  • voltage controlled lo-fi delay

  • octave adjustment per row

  • external audio input for one field

  • envelope follower CV output

Haloplane

Micro-loop sampler with seven adaptive fields

The Haloplane features seven customizable electromagnetic fields that emit short loops of audio. Each field is a micro-world of sound that can range from static oscillations to evolving textures.

  • micro-loop sampling and wavetable synthesis

  • pitch, length, position and modulation control for each field

  • voltage controlled Field Rotation rotates field positions around the surface

  • stereo voltage controlled multi-mode filter and audio effects

  • microphone and line input for instant sampling

  • Envelope and Modulation CV outputs

  • up to 100 user presets and scales

  • companion app with carefully curated library of samples, presets, and scales

  • USB audio interface for integration with any software

The Journey

This is us:

Passepartout Duo, a duo of musicians and instrument creators, who have been on a nearly continuous world tour since 2015. While continually downsizing our instrumentation to meet the practical needs of staying on the move, the Chromaplane came about from an ongoing research on percussion, analog synthesis, and sound installations.

We created the first Chromaplane in September 2021 - we were quickly inspired by how expressive and communicative it was, and started using it in our music.

We brought the Chromaplane all over the world: playing hundreds of concerts in more than fifty countries lead us to think about the Chromaplane beyond the context of just our duo.

KOMA Elektronik enters the picture:

We wanted to bring the Chromaplane to more people - so we teamed up with KOMA Elektronik. Together with KOMA, we successfully funded a first production run of 500 instruments through a month-long Kickstarter campaign.

The Chromaplane even won first prize at the Guthman Musical Instrument Competition in 2025! We hope the instrument can continue traveling, and make people more curious about unique ways of creating sound.

The process of releasing the Chromaplane brought about even more ideas for the potential of this interface.

That’s how we started working on the Haloplane, an electromagnetic instrument meant to explore digital sound design.
