Introducing Expressive-E Osmose 61

Now with 5 octaves. Same expressive power.

Published 12th November 2025

The new Expressive E Osmose 61 builds on the award-winning original, extended to 5 octaves for greater harmonic and melodic freedom — while retaining the same revolutionary expressive control that made the 49-key model a breakthrough.

Powered by the Haken Audio EaganMatrixsynthesis engine and featuring Expressive E’s unique 3D keybed, the Osmose 61 responds to every gesture — press, pitch-bend, vibrato, glide and more — delivering the most advanced MPE experience available today.

Now fully manufactured in-house at Expressive E’s new European facility in Poland, the Osmose 61 combines cutting-edge expressivity with the assurance of total quality control and long-term product stability.

• Now with 61 keys: increasing to 5 octaves for more for extended two-handed playing, complex arrangements and live performance freedom.
• Same innovation, bigger range: retains the expressive keybed, EaganMatrix engine, MPE integration and premium build quality of the original.
• Unmatched expressivity: independent pitch, pressure and gestural control on every key.
• MPE standard, redefined: built around MPE as its native language — not just compatible.
• Powerful standalone capabilities: onboard EaganMatrix engine, colour LCD, 500 factory presets (up to 2048 slots) and built-in effects — no computer required.
• Studio & stage ready: dual pedal inputs, DIN MIDI I/O, USB, balanced line outs, and a new optional soft case with wheels (coming soon).
