What does Firmware 2.3 actually add?
Expressive E's Osmose has always played two roles: a standalone synthesizer running Haken Audio's EaganMatrix engine, and an MPE controller for anything downstream. Firmware 2.3, a free update shipped September 24, 2026, pushes hard on the second role. The keybed now drives transport and the metronome, moves the playhead, sets loop points, and jumps between tracks, scenes and clips without touching a mouse. Selected-track mixing, track macros, undo and redo, and quantization and tempo control all sit under the same gestures that already handle pitch bend, pressure and glide. Expressive E also redesigned the USB-MIDI implementation for tighter DAW handshakes, added a bottom action bar for semitone transposition and performance-mode shortcuts reachable from any menu, and built in a DIN MIDI-to-USB MIDI interface function so an Osmose can bridge older gear into a modern setup.
Why does a keyboard with no synth engine matter now?
Five months before this update, Expressive E launched Osmose CE, a $999 (49-key) or $1,199 (61-key) version of the same keybed with the EaganMatrix engine stripped out entirely. No onboard synth, no standalone mode, nothing to play without a computer attached. At launch that read as a bet: that the keybed's per-note pressure, glide and aftertouch were worth real money sold purely as a controller. Firmware 2.3 is that bet paying off. A control surface that can drive a DAW's transport and mixer with the same expressive gestures it uses to bend a filter is a genuinely different pitch than a MIDI keyboard with more knobs. It also closes the gap between Osmose CE and the $1,799 flagship: buyers no longer have to think of "the synth" and "the controller" as separate categories, because the controller half now does meaningfully more.
What's actually in the free Ctrl-e bundle?
Every Osmose owner, CE or flagship, now gets a free Ctrl-e software license bundled with the update: no trial window, no subscription tier, no separate purchase. Ctrl-e ships with more than 900 expressive presets mapped for six third-party softsynth makers: Kilohearts, Synapse Audio, Dawesome, Applied Acoustics Systems, GForce and Vital. In practice, an Osmose owner can switch, track by track, between playing the onboard EaganMatrix engine and expressively controlling Vital's wavetables or an AAS physical model, without remapping a single control. That's a different posture from a gear market that increasingly treats firmware features as a tiered product, with extra charges or staggered rollouts common elsewhere in DJ and production hardware. Expressive E just gave its entire keybed line a bigger job to do, for free.
