The Expressive E Osmose is the standalone 49-key polyphonic synthesizer that set a new standard for musical expressivity — now available at a B-Stock price. After ten years of painstaking research, Expressive E emerged with a voltaic blend of historic craftsmanship and cutting-edge technology to revolutionize the approach to keyboard synthesis. Osmose is a 49-key synthesizer whose highly versatile sound engine is fueled by the powerful EaganMatrix, a digital modular engine developed by Haken Audio. Use intuitive gestures — press, bend, shake, strum, and more — to interact with keyboards and electronic sounds in a new organic way. Whether you're a veteran keyboardist, a workflow-oriented producer, or a daring sound designer, Osmose takes your musical journey to uncharted places, and it also functions as a powerful MPE controller for hardware and software synthesizers.

Key elements of its design:

• Augmented Keyboard Action (A.K.A.) Developed by Expressive E, the Augmented Keyboard Action is the technology inside every key, offering a seamless connection between every gesture and the resulting sound. Despite being electronic, Osmose feels more like an acoustic instrument to play — yet it retains the standard action and feel of a conventional MIDI keyboard.
• Three-Dimensional Polyphonic Expression Each of the 49 full-size keys offers 3D control: extended polyphonic pressure (sound as soon as you brush the keys), hi-resolution polyphonic aftertouch (a new sound variation past a pressure threshold), and polyphonic pitch control (vibrato and per-note bends by shifting keys left and right).
• EaganMatrix Sound Engine Expressive E partnered with Haken Audio to integrate its powerful EaganMatrix engine. This modular sound engine combines many types of digital synthesis — including physical modeling, FM, subtractive, and more — making it a deep, workflow-oriented soundbox.
• 500+ Custom Presets Osmose ships with more than 500 diverse presets plus 128 user slots, each manually customized with efficient macros and tailor-made to take full advantage of its unique keybed, with filters and sub-filters for easy browsing.
• Standalone & MPE Controller Modes Use it as a standalone synthesizer, an MPE MIDI controller, or a classic MIDI controller, with customizable sensitivity and velocity curves, a multi-mode MPE arpeggiator, and an innovative pressure glide feature — all configurable directly on the unit without a computer.
• Onboard Effects & Editing Digital stereo effects let you select between reverb, mod delay, swept echo, analog echo, or LPF/HPF delay. While Osmose has near-limitless onboard control, the accompanying Haken Audio EaganMatrix editing software lets you dive even deeper into its synthesis architecture.

Reviewing it, Sweetwater highlighted the Osmose's uncompromising approach to total polyphonic aftertouch, noting that unlike other MPE-capable keybeds, Osmose retains the standard action and feel of a conventional MIDI controller or keyboard — with each key having an extended range of motion from its resting point for continued expression through an assigned value.
