Expressive E, in collaboration with Haken Audio, releases Osmose, the new standard for musical expressivity. This standalone polyphonic synthesizer unlocks new ways to control sound with familiar gestures (press, bend, shake, & more). It features a deep sound-design engine and hundreds of ready-to-use, innovative presets. It also functions as a powerful controller for hardware & software synthesizers.

Product description

Combining traditional craftsmanship with modern technology, Osmose is the result of more than 10 years of research and development, as well as feedback from world-class artists. Osmose introduces new physical gestures, allowing musicians to interact with sounds and produce music. It does this while not only respecting, but also enhancing the playerʼs existing keyboard skills. Every note can be articulated independently with unique expressive possibilities.

The EaganMatrix Sound Engine

Offering new levels of expressivity required a seamless interaction between Osmoseʼs unique keybed mechanism and its sound engine. Logically, Expressive E has partnered with Haken Audioto integrate its powerful EaganMatrix sound engine with Osmose.

Its modular sound engine combines many types of digital synthesis (including physical modeling, FM, and more), making it a workflow-oriented soundbox. Osmose ships with more than 500 presets, and each of them has been manually customized with efficient macros that open new realms of sound exploration.

A playful playing experience

All the internal sounds in Osmoseʼs large library are tailor-made to take advantage of its unique keybed. Osmoseʼs unique sound identity is a combination of highly detailed acoustic, electronic, and hybrid sounds that will easily add nuances and variations to any music genre.

These sounds were carefully crafted to react to a playerʼs slightest movements and make use of the keysʼ three-dimensional sensitivity in a unique way to create effects such as strummed notes, vibrato, legato, layered dynamics, and much more. As a result, discovering and controlling Osmoseʼs sounds is refreshing and fun!

Built to empower external synths

On top of being a traditional MIDI keyboard controller, Osmose can also interface with computers and other instruments as an MPE MIDI controller. It also offers polyphonic aftertouch support, a Multichannel MIDI mode, and global pitch bend. All of these changes can be made directly from the Osmose interface, with no need for a computer.
