Expressive E Osmose 49-Key Polyphonic Synthesiser MIDI Controller

Expressive E and Haken Audio have redefined musical expression with the Osmose, a groundbreaking 49-key polyphonic synthesiser that responds to three-dimensional touch control. This innovative instrument combines traditional keyboard skills with revolutionary gesture-based sound manipulation, allowing musicians to press, bend, shake and articulate each note independently. The result of over a decade of research and development, informed by feedback from world-class artists, Osmose bridges the gap between familiar playing techniques and cutting-edge musical expression.

At the heart of Osmose lies Haken Audio's powerful EaganMatrix sound engine, a modular digital synthesis platform that encompasses subtractive, FM and physical modelling synthesis methods. The instrument ships with over 500 factory presets, each manually customised with efficient macros that unlock new sonic territories. These sounds are specifically crafted to respond to the keybed's unique three-dimensional sensitivity, creating natural effects like strummed notes, vibrato, legato passages and dynamic layering that react to the player's slightest movements.

Beyond its standalone capabilities, Osmose functions as a comprehensive MIDI controller supporting MPE (MIDI Polyphonic Expression), polyphonic aftertouch, and traditional MIDI modes. The instrument features 24 voices of polyphony, assignable mod and pitch sliders, a multi-mode MPE arpeggiator, and digital stereo effects including reverb, delays and filters. With its large colour display, nine push encoders, dual line outputs, headphone output, and pedal inputs, Osmose provides professional connectivity and control options suitable for both studio and live performance applications.
