Expressive E Osmose 61 61-Note Expressive MPE Polyphonic Synthesizer

The Osmose 61 expands upon the worldwide success of the 49-key version, adding an extra octave for greater freedom in performance and composition — while retaining everything that defined the original:

• The fully expressive 3D keybed with complete MPE control (press, pitch bend, vibrato, glide, etc.)
• The powerful EaganMatrix engine by Haken Audio
• A premium European build, with production now fully internalized in our new Polish facility, ensuring total quality control and long-term stability

Osmose sits at the heart of an evolving ecosystem enriched through collaborations with U-He, KiloHearts, AAS, Dawesome, and Synapse Audio, as well as proprietary Expressive E software like Noisy 2 and Soliste.

This dynamic environment continues to grow with regular firmware updates, new sound libraries, and — coming soon — a series of mini-synths with intuitive editors for the EaganMatrix, designed to make sound design more accessible than ever.

These developments are transforming what was once a complex synthesis environment into an expressive, user-friendly platform that empowers creativity.

Redefining musical expressivity, the Osmose sets the new benchmark. Powered by the EaganMatrix engine, it offers the full expressive experience, as a standalone synthesizer or the most advanced MPE controller. Press, bend, shake, strum, and more to play keyboards and electronic sounds with a natural, unique organic feel.
