description Expressive E Osmose 49 Overview
Expressive E's Osmose 49 combines a familiar-looking keyboard with an unusually responsive playing action. Its 49 keys sense pressure and sideways movement, allowing notes to change in character and pitch under the fingers. Polyphonic aftertouch provides independent pressure information for different held notes. It also contains an EaganMatrix sound engine, so it functions as a standalone synthesizer as well as a MIDI controller for compatible external instruments.
Synthesists and producers seeking detailed modulation can use the keyboard to shape a phrase as it is played, rather than adding every change afterward in recording software. MPE support carries individual-note expression into suitable hardware and software setups. The defining feature is the pairing of conventional key shapes with deeper touch control and an internal synth. That makes it relevant to keyboard players who want expressive sound shaping without adopting a continuous playing surface.
help Expressive E Osmose 49 FAQ
What built-in synthesizer engine is included with the Expressive E Osmose 49?
The Osmose includes the Haken Audio EaganMatrix sound engine built directly into the hardware. This allows it to function as a fully standalone synthesizer without needing a computer. The engine is specifically designed to take full advantage of the keyboard's expressive MPE capabilities.
How does the Expressive E Osmose 49's key action differ from a standard MIDI keyboard?
The Osmose features a custom keybed that allows for multidimensional polyphonic expression (MPE). Unlike standard keyboards, each key can detect pressure (aftertouch), lateral movement (pitch slide), and forward/backward movement. This gives musicians precise, per-note control over pitch, timbre, and modulation.
Can the Expressive E Osmose be used to control other software synthesizers?
Yes, alongside its internal sounds, the Osmose functions as a highly advanced MPE MIDI controller. It connects via standard USB or traditional 5-pin MIDI outputs to control external hardware synthesizers. It is fully compatible with modern MPE-supported software like Spectrasonics Omnisphere and Apple Logic Pro.
How many keys does the Expressive E Osmose have?
The Expressive E Osmose has 49 full-sized, velocity-sensitive keys. They are designed with a semi-weighted action to mimic a traditional piano while remaining highly responsive to nuanced physical manipulation. The keybed provides a highly tactile experience for studio production and live performance.
