Serious Musical Expression for Serious Creators
We’ve gotten our hands on every MIDI controller under the sun here at Sweetwater, and it’s not often that one fundamentally reimagines what it means to play a keyboard instrument. Well, in true Expressive E fashion, the Osmose CE does just that, melding the award-winning expressive keybed technology from the company’s Osmose synthesizer with an endlessly expressive MIDI controller. Brandishing MIDI Polyphonic Expression (MPE), the Osmose CE delivers articulate per-note control, enabling you to bend individual notes within a chord, add finger-controlled vibrato, shape dynamics through pressure, and sculpt every phrase with intuitive gestures. The Osmose CE is fueled by Ctrl-e, a free companion software ecosystem developed exclusively for Osmose CE, bolstered by more than 900 performance-ready expressive presets, 8 pre-mapped macros per preset, and deep integration with leading sound engines from developers — all accessible the moment you plug in. Whether you're working in MPE, traditional MIDI, or taking command of your DAW, the Osmose CE adapts flawlessly to your workflow. Showcasing an eye-catching white aluminum top and black base, the Expressive E Osmose CE is the perfect MIDI controller for producers, composers, sound designers, and live performers who refuse to compromise between inspiring sounds and truly liberating musical expression.

Play every note the way you feel it
Creators familiar with Expressive E’s award-winning Osmose synthesizer will find the Osmose CE quite familiar, as it uses the same expressive keybed technology. Under your fingers, the Osmose CE feels like you’re playing rather than merely controlling. Thanks to MPE support, you’ll revel in the freedom afforded by this keyboard’s per-note control, which elevates it far beyond basic velocity and aftertouch, responding not just to where you play a note but to how hard you press it, bend it, and release it. Through a full suite of gestural controls — Tap, Press, Pitch Bend, Vibrato, Shake, Strum, and Expressive Note-off — you’ll be able to bend single notes inside a chord, add vibrato directly with your fingers, and shape phrases with the kind of dynamic nuance typically reserved for acoustic instruments. With the Osmose CE, every gesture becomes part of your performance, transforming the keyboard from a trigger into a truly expressive instrument.


Experience a deeper, more expressive approach to playing
Equally at home in MPE, traditional MIDI, and as a DAW controller, the Expressive E Osmose CE will level up your performance setup, providing you with a deeper, more expressive approach to playing. Not only does the Osmose CE unlock full per-note articulation with MPE-enabled instruments, but it also adds expressive nuance to your other software and hardware instruments. Additionally, you get an MPE Arpeggiator, which keeps every arpeggiated note independent and responsive in real time across both MPE and standard MIDI. Moreover, Press Glide allows you to glide naturally between notes using pressure alone, replacing rigid portamentos with something far more organic and musical. Beyond that, the Osmose CE performs admirably as a fully integrated control surface inside your DAW, tackling transport control, track and device navigation, mixer control, and macro access with equal aplomb. Boasting flawless compatibility with Ableton Live, Cubase, Bitwig, and Logic Pro, the Osmose CE ensures that you’ll never break creative momentum again by reaching for your mouse.
A sound ecosystem that speaks your language
At the core of the Osmose CE is Expressive E’s revolutionary Ctrl-e companion app, unlocking a dedicated sound ecosystem built from the ground up to match the expressive capabilities of the Osmose CE’s keybed. Replete with more than 900 meticulously crafted presets, a dynamic preset browser, and eight pre-mapped macros per preset, every sound in Ctrl-e is designed to respond naturally to the full range of gestural control the keybed offers — no generic MIDI mappings, no technical configuration, just performance-ready sounds that feel alive from the very first note. Ctrl-e’s library leverages a curated collection of industry-leading sound engines and partner developers, including Expressive E, Synapse Audio, AAS, Kilohearts, GForce, Dawesome, and Vital, to craft a broad cache of sonic textures and synthesis approaches, all unified within a single, cohesive environment. Lastly, since the Osmose CE is able to switch seamlessly between Ctrl-e, MPE, and traditional MIDI, you’ll benefit from on-the-fly setup recall and instant adaptation to different playing styles with nothing to break your creative stride.
