    Expressive E Osmose 3D Polyphonic Synthesizer

    6 In Stock

    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 player’s 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 Osmose’s unique keybed mechanism and its sound engine. Logically, Expressive E has partnered with Haken Audio to integrate its powerful EaganMatrix sound engine with Osmose.

    Its modular sound engine combines many types of digital synthesis (including physical modelling, FM, and more), making it a workflow-oriented soundbox. Osmose ships with more than 500 preset, 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 Osmose’s large library are tailor-made to take advantage of its unique keybed. Osmose’s 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 player’s slightest movements and make use of the keys’ 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 Osmose’s 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.
