Expressive E Osmose 61 — five full octaves of three-dimensional expression

Osmose 61 is a 61-key polyphonic digital synthesizer with the patented A.K.A. (Augmented Keyboard Action) 3D keybed. The five-octave range opens up two-handed playing, complex arrangements, and live performance without range compromises. Every expressive capability of the Osmose 49 — unchanged. Runs as a standalone synthesizer, MPE controller, or classic MIDI controller.

Overview

On a standard keyboard, a note is a binary event: press, sound, decay. What happens inside the note — dynamic movement, vibrato, crossfading between layers — depends entirely on LFOs and envelopes, not your fingers. Osmose 61 changes that relationship at its root — across the full span of five octaves.

Each of the 61 keys responds across three simultaneous axes: vertical pressure (velocity and aftertouch), post-threshold press (pressure glide, layer crossfading), and lateral movement (per-note vibrato and pitch bend without the pitch wheel). Every note in a chord carries its own isolated expression channel — not a global aftertouch signal, but full MPE per finger.

The extra octave over the 49-key model solves a specific problem: keyboardists working on harmonically complex arrangements, film composers layering textures, and two-handed instrumentalists all hit the four-octave boundary precisely when their expressivity was already in reach.

Key Features

Augmented Keyboard Action (A.K.A.) — 61 keys
Patented keybed mechanism with raised key stems, developed exclusively for Osmose. Sound is generated from the first touch — before the note officially triggers — with no dead zones and no thresholds. Five full octaves with no compromise in expressive mechanics.

EaganMatrix sound engine by Haken Audio
The same DSP engine powering the Haken Continuum, a reference instrument in expressive synthesis. Physical modelling, FM, subtractive, additive, granular — all within one multi-layered environment. Six dedicated SHARC DSP chips, up to 24 voices of polyphony.

Full per-note MPE on every key
Pitch bend, aftertouch, pressure glide, and vibrato are fully independent for each note in a chord. Osmose operates in three modes — standalone synth, MPE controller, or classic MIDI controller — switchable without rebuilding the setup.

580 factory presets with macro controls
Every preset is hand-tuned for the A.K.A. keybed with pre-mapped macros for fast editing of timbre, texture, and effects. The library covers physically modelled winds and strings, FM, pads, basses with the dynamics of a bass guitar, and SFX for sound design.

Built-in FX chain
Reverb, delay, compressor/drive, two convolution engines, pre- and post-reverb/delay processing, shelving EQ — ready without an external processor.

Haken Editor (Mac/PC)
Advanced environment for building sounds from scratch, beyond what is accessible directly from the instrument panel. For sound designers who want to go deeper than factory presets.

USP: five octaves — what the extra range actually changes

On a standard synthesizer, a missing octave is a melodic range issue — workable with transposition. On Osmose, it is a fundamentally different problem. Three-dimensional expression works best when both hands operate simultaneously — left hand holding a chord with its own aftertouch and pressure glide, right hand playing a melody with per-note vibrato. At four octaves, this technique ran out of space quickly.

Osmose 61 resolves this without compromise. Five octaves provide room for full two-handed work across the complete harmonic range: wide voicings, bass in the left hand with independent pressure glide, tenor voices in the middle, melodic line with vibrato at the top — all within a single instrument, without shifting octaves mid-phrase.

For film composers and sound designers, this is the difference between sketching textures and doing real arrangement work in real time. The instrument is assembled at Expressive E's own facility in Poland — full manufacturer quality control from design to final assembly.
