A new generation of MIDI controllers
Osmose CE combines Expressive E's acclaimed expressive keybed technology with Ctrl-e, a new sound ecosystem built for expressive playing.
It is designed for musicians who seek deeper expression beyond conventional control : a more physical, nuanced, and an inspiring way to interact with software instruments, plugins, and modern studio setups.
With MPE, Osmose CE unlocks true per-note expression. It also expands the expressive range of the instruments musicians use daily within traditional MIDI workflows.
Available in 49-key and 61-key versions, Osmose CE is designed to make expressive playing feel immediate, musical, and natural.
Why Expressive Playing Starts Here
Expressive playing in software has always been very difficult to access.
Even when the sounds were inspiring, the experience was often held back by complex MPE setups, inconsistent compatibility, and complicated workflows that were too technical to be truly immediate.
Osmose CE fixes that.
By combining an extraordinary expressive keybed with Ctrl-e, its dedicated sound ecosystem, Osmose CE gives musicians immediate access to a large library of expressive, performance-ready sounds designed to respond naturally from the very first note.
No complicated setup.
No plugin-by-plugin configuration.
No need to build an expressive workflow from scratch.
In short:
Osmose CE makes expressive playing truly immediate, fully accessible, and far easier to integrate into real-world music creation.

A keyboard unlike any other
Osmose CE uses the exact same expressive keybed technology as the award-winning Osmose synthesizer. Same engineering. Same responsiveness. Same philosophy: music should feel like playing, not like controlling.
Players can bend a single note inside a chord, add vibrato directly with their fingers, and shape phrases with the kind of nuance usually associated with acoustic or expressive instruments. Osmose CE responds not only to where a note is played, but to how it is pressed, bent, and released, turning each gesture into part of the musical performance.
Ctrl-e: the sound ecosystem built for Osmose CE
Osmose CE works effortlessly with Ctrl-e, the free companion software developed by Expressive E for expressive music creation.
Ctrl-e is not just bonus software.
It is a core part of the Osmose CE experience.
Included with Osmose CE:
● 900+ expressive presets
● Dynamic preset browser
● 8 pre-mapped macros per preset
● Deep hardware/software integration
Each sound is carefully designed to respond naturally to the expressive gestures of the Osmose keybed.
No generic mappings.
No technical setup.
Just expressive sounds, ready to play.
Powered by industry-leading sound engines
Ctrl-e gives musicians access to a curated ecosystem of expressive sound engines and partner instruments.
Supported technologies and developers include:
● Expressive E
● Synapse Audio
● AAS
● Kilohearts
● GForce
● Dawesome
● Vital
Together, they provide a broad range of sonic identities and synthesis approaches, all unified in one performance-ready environment.
Plug in. Play.
Osmose CE is designed to work seamlessly with the setup musicians already have.
It can easily switch between Ctrl-e, MPE, and traditional MIDI workflows, adapting to different playing styles and recalling dedicated setups without interrupting the creative flow.
The goal is simple:
Less setup. Less friction. More playing.
Bring greater expression to the instruments you already use
Osmose CE is designed to work naturally in both MPE and more traditional MIDI environments.
With MPE-compatible instruments, it unlocks full per-note expression. But it also makes expressive playing far more accessible across many of the plugins, instruments, and hardware musicians already use every day.
It’s not about replacing your setup.
It’s about rediscovering it through more expressive playing.
Expressive performance tools built in
Osmose CE includes advanced performance tools that extend the expressive possibilities of the keyboard.
MPE Arpeggiator
A uniquely expressive arpeggiator where every note remains independent and responsive in real time, in both MPE and standard MIDI workflows.
Press Glide
A unique performance feature that allows players to glide naturally between notes using pressure, rather than relying on fixed portamento times.
Together, these tools open up a more fluid and expressive way of shaping performance directly from the keyboard.
Smart DAW integration
Osmose CE also includes integrated DAW controls designed to keep musicians immersed in the creative moment, without constantly reaching for a mouse or a second controller.
Supported workflows include:
● Transport controls
● Track and device navigation
● Mixer control
● Macro access
● Automatic DAW detection
Compatible DAWs include:
● Live 12+
● Cubase 15+
● Bitwig 5+
● Logic Pro 12+

With its white aluminium top, black base, and carefully engineered construction, Osmose CE is built for musicians who expect both precision and durability from the tools they use every day.
Production and design are handled in Europe by the Expressive E team, ensuring close control over build quality and long-term consistency.
Two sizes, same expression
Osmose CE is available in 49-key and 61-key versions, both offering the exact same expressive technology and core experience.
