Expressive E Osmose 61-key Polyphonic Synthesizer and MIDI Controller
The Expressive E Osmose 61-key synthesizer puts detailed, three-dimensional control beneath every note. Its full-size 61-note keybed combines polyphonic aftertouch with the Haken Audio EaganMatrix digital modular engine, while onboard sounds, effects and hands-on controls make expressive performance accessible from the keyboard itself.
Shape Every Note
Firstly, each key responds to polyphonic aftertouch, with extended vertical movement and horizontal modulation available per note. That lets you add independent expression across chords and melodic lines. Meanwhile, customisable sensitivity profiles and response curves make the keybed feel more personal for different patches and playing styles.
Explore a Deep Sound Engine
Moreover, powered by the Haken Audio EaganMatrix digital modular engine, the synthesizer includes more than 500 factory presets and space for up to 2048 slots. The sound library covers FM synthesis, physical modeling and more, with each EaganMatrix sound tailored to the instrument’s expressive controls.
Stay Hands-On While You Edit
Furthermore, a large color LCD screen sits alongside backlit buttons, clickable knobs and pitch/modulation sliders. Thus, keeping sound selection and patch editing within easy reach. You can adjust velocity curves, sensitivity, expressivity, effects and more, then save and recall patches for a setup that suits your playing.
Connect to Your Setup
Use the Osmose as a standalone synthesizer or as an MPE MIDI keyboard controller through its MIDI in, out/thru and USB connections. Two audio outputs handle stereo playback, while the front headphone output has dedicated volume adjustment. Two pedal inputs add assignable continuous, sustain or synth control.
