For years, the conversation around the Expressive E Osmose centered on two things at once: a genuinely novel touch-sensitive keybed capable of continuous per-note pitch, pressure, and timbre, and the EaganMatrix synth engine humming inside it. In April 2026, Expressive E split those two ideas apart. The result is the Osmose CE (Controller Edition), a 49-key MPE controller that keeps the keybed and drops the internal sound engine entirely, bringing the price down to $999.

Why Remove the Synth?

The decision reflects something Expressive E clearly heard from its own user base: for a large share of Osmose owners, the magic was always the keybed itself — the way it reads finger pressure, lateral movement, and post-touch depth as continuous, per-note data — rather than the EaganMatrix synthesis engine bundled inside. Plenty of players were routing Osmose as a controller into other software anyway. The CE formalizes that use case and removes the cost of components most buyers weren't using.

What's left is the part that made Osmose distinctive in the first place: a keybed that behaves like a real piano action at rest but adds continuous MPE dimensions the moment you start pressing, sliding, or leaning into a note. That's a meaningfully different physical proposition than silicone-surface controllers, and it's aimed squarely at keyboardists who want expressive control without abandoning the muscle memory of a weighted key.

The Ctrl-e Bet

Instead of an onboard engine, the Osmose CE leans entirely on Ctrl-e, Expressive E's software ecosystem, which now ships with more than 900 partner presets mapped specifically to the keybed's expressive range. That's a bet that the value has shifted from hardware synthesis to a curated software layer — a trend that mirrors what's happened elsewhere in the MPE controller market, where manufacturers increasingly treat the controller as a gesture-capture device first and a sound source second, if at all.

Where It Sits in the Market

The Osmose CE lands into a genuinely competitive field of 2026 MPE controllers, each with a different physical philosophy:

Roli Seaboard Rise 2 ($1,399) uses a continuous silicone surface rather than discrete keys, offering the widest range of continuous pitch and timbre gestures but the steepest learning curve for players coming from a traditional keyboard background.

LinnStrument 200 ($1,499) trades keys entirely for an isomorphic grid, which tends to resonate most with guitarists, percussionists, and anyone curious about non-Western tunings and alternate note layouts.

Haken Continuum Slim 21 ($1,799) offers the fingerboard-style continuous surface the Continuum line is known for, now in a more compact 21-note footprint.

Against that field, the Osmose CE is the option that asks the least behavioral adjustment from a pianist while still delivering full per-note MPE data — pitch bend, pressure, and timbre — to whatever synth or DAW instrument is on the receiving end.

What This Means for MPE Players

The broader signal here is worth paying attention to. A controller-only edition at a meaningfully lower price point makes serious MPE hardware more accessible to musicians who already have synths and plugins they like and simply want a better way to play them expressively. Pair the Osmose CE with any of the growing list of MPE-aware software instruments, and you get continuous, per-note control without paying for a sound engine you weren't going to use.

It also raises a reasonable question for the rest of the market: if the keybed and gesture-capture technology is what players actually value, will other controller makers follow with their own stripped-down, controller-only editions? For now, Expressive E has drawn a clear line between hardware feel and software sound, and the $999 price point puts genuinely expressive per-note control within reach of a wider set of players than the original Osmose ever did.

For musicians evaluating their first serious MPE controller, the Osmose CE is worth auditioning specifically for its keybed feel — it's the closest thing on the market right now to "acoustic piano touch with continuous expression layered on top," and that combination doesn't have many direct competitors.
