After 10 years of research and development in France, modern luthiers Expressive E offer with Osmose a new way to approach keyboard instruments. This standalone MPE synthesizer has been designed to make its 49 expressive keys interact perfectly with the powerful EaganMatrix sound engine (developed by the expressive pioneers at Haken Audio), a digital modular engine developed by Haken Audio. Delivered with more than 500 MPE presets, integrated effects and intuitive and fun parameterization functions, Osmose allows you to sculpt the sound in depth thanks to the use of simple MPE gestures. The new generation polyphonic aftertouch allows 3D control of each key on several axes. You can also use its innovative keyboard in MIDI control to control your DAW and your favorite synthesizers (virtual or hardware)! Expressiveness is at the heart of the young French brand Expressive E. We owe it the famous Touché and Touché SE, probably the best-designed tools to bring a game rich in expressions, nuances, modulations, to most synthesizers on the market or virtual instruments.
Starting this year 2023, musicians and creators around the world will be able to benefit from the know-how of Expressive E with Osmose, designed in partnership with Haken Audio.
With Osmose, the ultimate controller AND new-generation synthesizer, your inspiration will be increased tenfold and the organic and rich sounds it produces will be played, controlled, with unparalleled finesse and subtlety.
It's a revolution!

About Expressive E
Expressive E is a French electronic instrument manufacturer whose mission is to improve the way musicians interact with sound by creating much more intuitive and powerful music creation tools.
Their goal is to enable a seamless connection between artists and their instruments.
Expressive E created the award-winning Touché and Touché SE MIDI controllers, as well as the Arché range of modeled instruments and multiple creative sound banks, including the MPE collection.
Their first standalone hardware synthesizer, Osmose, sets a new standard for musical expressiveness and pushes the boundaries of keyboard creativity. It is an easy-to-use electronic instrument
that opens new avenues for controlling sound through familiar gestures (tap, bend, shake, etc.). Osmose offers multidimensional control of each note while respecting the player's original skills on the keyboard.

About Haken Audio

Prior to the partnership with Expressive E, Haken Audio’s EaganMatrix sound engine was exclusively reserved for the company’s Continuum Fingerboard and ContinumMini instruments.

Haken Audio’s team members each have over 25 years of experience in experimental sound design.
Founder Dr. Lippold Haken began working on the Continuum in the early 1980s, and over the last decade he has worked with Edmund Eagan to develop the EaganMatrix, a modular synthesizer-inspired sound engine optimized for the three-dimensional finger movements of the Continuum Fingerboard.
