Expressive E introduces the Osmose 61

The new Osmose 61 adds an extra octave to the 3d keybed of the acclaimed MPE synthesizer from Expressive E

Expressive E unveils the new Osmose 61: one more octave, infinite expression.

Building on the worldwide success of the 49-key Osmose, the new 61-key version adds an extra octave, giving musicians more room to explore, compose, and perform. Musicians can now choose between the original 49-key or 61-key model, depending on their needs and playing style.

Beyond the instrument itself, Osmose thrives within a living, evolving ecosystem of software, presets, and community-driven updates, ensuring it grows and improves over time. And with production now fully internalized in a new Polish factory, Expressive E guarantees the highest European quality standards for every instrument.

Osmose 61: A Bigger Range, Same Innovation

With 61 keys, Osmose 61 offers greater harmonic and melodic freedom, perfect for two-handed playing, complex arrangements, and live performance. It retains everything that made the 49-key model revolutionary: the expressive 3D keybed, MPE integration, high-end interface, and premium build quality — giving musicians the choice to stay with 49 keys or step up to 61.

Unmatched Expressivity

Developed and fully designed by Expressive E, the Osmose keybed sets a new benchmark for MPE instruments. Every note responds with nuance to velocity, press, aftertouch, pitch bend, pressure glide, strum, vibrato, and more — making the keyboard a natural extension of the player’s hands.

Multi-Oscar-winning composer Hans Zimmer has already tapped into its expressive potential on landmark projects such as the Dune: Part Two soundtrack.

“You guys spent an enormous amount of time building exactly the instruments that should have been built a hundred years ago.” — Hans Zimmer

EaganMatrix Always at the Core of Osmose Sound

Powered by the legendary EaganMatrix engine, developed by Haken Audio, Osmose delivers rich acoustic textures and complex synth sounds that react intuitively to every gesture. Its versatile engine supports physical modeling, FM, subtractive synthesis, and more, complemented by onboard reverb, delay, compressor, and EQ.

With 580 factory presets and up to 2048 preset slots, Osmose offers a complete, performance-ready palette while staying true to the expressive soul of the instrument.

A Living Ecosystem

Osmose is more than an instrument; it is at the center of a living ecosystem that grows and evolves with its community of musicians.

Expressive E has expanded the software ecosystem around Osmose, offering a rich library of sounds through partnerships with renowned companies such as U-He, KiloHearts, Dawesome, AAS, and Synapse Audio. These collaborations are featured in the Expressive Suites, available on the Expressive E website.

Proprietary software explicitly designed for Osmose — such as the new Soliste (physically modeled solo strings) and Noisy 2 (a dual-layer, noise-driven synth) — has also been released to further expand musical possibilities.

This ecosystem is designed to grow. Expressive E is committed to making Osmose evolve over time, with regular firmware updates bringing smoother workflows, deeper DAW integration, and an ever more fluid user experience.

Coming soon, a series of mini-synths with intuitive editors for the EaganMatrix will make sound design more accessible than ever, transforming what was once a complex interface into an expressive, user-friendly platform for creativity.

Made in Europe: A New Factory in Poland

Until now, Osmose production has been outsourced to China. To meet global demand while guaranteeing uncompromising quality, Expressive E is taking a decisive step forward: a new assembly facility in Poland, fully dedicated to Osmose and future instruments.

For the first time, the company will no longer rely on subcontractors. Every stage, from design to assembly, will now be handled in-house. This shift gives Expressive E full control over the lifecycle of its products, ensuring reliability, sustainability, and the highest European quality standards.

It’s an ambitious challenge for a young company, but one driven by passion, conviction, and a clear vision: to craft instruments that embody both innovation and integrity, from the very first design to the final note — and to gain even greater freedom to innovate.
