Expressive E Osmose 49-Key MPE Synthesizer & MIDI Controller

Expressive E Osmose 49-Key – MPE Expressive Synthesizer & Controller

The Expressive E Osmose 49-Key is a next-generation polyphonic synthesizer and MIDI controller designed around an entirely new concept of keyboard expression. It combines a unique 3D-responsive keybed with a powerful internal synthesis engine, enabling musicians to shape sound through pressure, movement, and gesture rather than traditional key velocity alone.

Revolutionary 3D Expressive Keybed

At the core of the Osmose is its 49-key full-size keybed with three-dimensional sensing. Each key responds not only to press velocity but also to continuous pressure, lateral movement, and expressive gestures such as vibrato, pitch bend, and note articulation. This allows every note in a chord to be independently shaped in real time, creating performance expression closer to acoustic instruments.

EaganMatrix Sound Engine

The Osmose features the EaganMatrix synthesis engine developed by Haken Audio. This modular digital engine supports multiple synthesis methods including physical modeling, FM, and subtractive synthesis. It is deeply integrated with the expressive keybed, allowing sound parameters to respond directly to finger movement and pressure changes.

Standalone Synthesizer and MPE Controller

The instrument operates in multiple modes: a fully standalone polyphonic synthesizer, a MIDI Polyphonic Expression (MPE) controller, or a traditional MIDI keyboard. This flexibility allows it to function both as a production instrument and as a control surface for software and hardware synths.

Deep Expressive Performance Control

Osmose introduces advanced gesture-based performance controls such as pressure glide, note-off modulation, vibrato shaping, and per-note pitch manipulation. These features allow highly nuanced performances without external modulation wheels or complex MIDI mapping.

Sound Library and Presets

It includes a large library of factory presets designed specifically for expressive playing, covering acoustic, electronic, and hybrid sounds. Each preset is optimized to respond to the instrument’s 3D keybed, ensuring immediate playability without deep programming.

Studio and DAW Integration

Beyond its standalone engine, the Osmose functions as a powerful controller for software instruments and DAWs. It supports standard MIDI, MPE, USB connectivity, and traditional DIN MIDI, making it compatible with professional studio environments.

Designed for Expressive Musicians

The Osmose is built for performers, composers, and sound designers who want a more physical and expressive relationship with synthesis. It bridges the gap between keyboard instruments and continuous expressive controllers, offering a fundamentally different playing experience.
