Expressive E Osmose 61 CE

Yes, the Osmose 61 CE features MPE-compatible key per-note expression, making it an excellent controller for MPE-aware instruments like Arturia Pigments, Spectrasonics Omnisphere, and Expressive E's own Expressive E Factory library. Each of the 61 keys can send independent pitch bend, slide, and pressure data simultaneously, unlike traditional MIDI keyboards that share a single channel.

The Osmose is primarily a MIDI controller, but it also ships with Expressive E's standalone plugin synth called Eaganlyser, which runs embedded on the hardware so you can play sounds without a computer. This makes it a hybrid device — it works as a pure MIDI controller over USB or DIN MIDI, but also generates its own sounds when powered on without a DAW.

The Osmose uses a traditional-feeling keybed with a hard plastic key surface combined with per-key pressure sensing and aftertouch, whereas the Roli Seaboard uses a continuous soft silicone surface that also responds to lateral sliding. Osmose targets keyboardists who want familiar piano-like key travel with expressive depth, while the Seaboard caters to players who want a continuous, pliable playing surface.

The Osmose is class-compliant over USB and works with all major DAWs including Ableton Live, Logic Pro, Cubase, and Bitwig Studio. For full MPE support, you'll want to use DAW versions released after around 2018, when MPE was widely adopted across these platforms.
