Instruments for daydreaming

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

Chromaplane

Electromagnetic 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.

Haloplane

Electromagnetic micro-loop sampler

We’ll be showing the Haloplane at Superbooth 26 (booth O400) in Berlin. To be the first to hear about features, pricing, and availability, please provide us with your email below.

Where can I get one?

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.
