Essential facts about the Osmose 61 synthesizer
- One more octave: 61 full-size keys for broader harmonic range, two-handed playing and extra freedom on stage.
- Unique 3D expressivity: each key responds to velocity, pressure, lateral pitch, glide and vibrato for reference-class MPE control.
- Built-in EaganMatrix engine: acoustic textures, physical modeling, FM and subtractive tones ready to perform without a computer.
- Designed and assembled in Europe: premium build, refined interface and an ever-evolving software ecosystem.
Historical context and lineup position
Osmose 61 extends the breakthrough 49-key model that redefined expressive keyboards. It adds a full octave while preserving Expressive E’s philosophy: a mature MPE instrument with a three-dimensional keybed powered by Haken Audio’s EaganMatrix. With production internalized in a new Polish factory, the brand gains industrial control and reliability, cementing its flagship status in premium expressive synths.
Who is this synthesizer for
Perfect for advanced players, composers and sound designers seeking nuanced gestural control. Excels in ambient, electronic, techno, synthwave, modern pop and film scoring. In studio and on stage, Osmose 61 shines as a standalone synth, MPE controller or standard MIDI controller in hybrid rigs.
Features and what’s new
The 61-key keybed offers more room while keeping Osmose’s signature 3D response: tap, press, aftertouch, per-note lateral pitch bend, pressure glide, vibrato and detailed note-off behavior. The EaganMatrix engine spans organic modeling, FM and complex subtractive architectures, enhanced by onboard effects (reverb, delay, drive/compressor, EQ and convolution). An expressive arpeggiator brings lively phrasing. The interface combines a color LCD, six encoders, pitch/mod sliders and direct octave/preset access to navigate 580 factory sounds and up to 2048 slots. Dedicated tools like « Soliste » and « Noisy 2 » and partner suites expand the palette. As a controller, Osmose 61 speaks MPE natively, integrates via USB or DIN MIDI and fits DAW workflows. Two assignable pedal inputs and line/headphone outputs round out a stage-ready design.
