The Expressive E Osmose 61 CE is the expanded 61-key version of one of the most innovative synthesizers of recent years — a keyboard synthesizer and MPE controller that breaks new ground with its revolutionary 3D keybed. Building on the success of the 49-key Osmose, the new 61-key version adds an extra octave, giving musicians more room to explore, compose, and perform two-handed. It retains everything that made the original revolutionary: the expressive 3D keybed, MPE integration, high-end interface, and premium build quality. Osmose is a 61-key synthesizer whose highly versatile sound engine is fueled by the powerful EaganMatrix, a digital modular engine developed by Haken Audio — the same engine used in Haken's Continuum. This "CE" version is proudly made in Europe (Poland).

Key elements of its design:

• Revolutionary 3D Keybed Developed and fully designed by Expressive E, the Osmose keybed sets a new benchmark for MPE instruments. Each key individually processes press, glide, aftertouch, and pitch bend, allowing users to manipulate and articulate sounds in a way never before possible with a traditional keyboard — a livelier, more nuanced performance similar to that of an acoustic instrument.
• Extra Octave of Range With 61 keys, Osmose 61 offers greater harmonic and melodic freedom, perfect for two-handed playing, complex arrangements, and live performance, while retaining the exact expressive capabilities of the 49-key model.
• EaganMatrix Sound Engine Both Osmose synthesizers are powered by the EaganMatrix engine developed by Haken Audio. This versatile digital modular engine supports physical modeling, FM, subtractive and additive synthesis, and more, with each preset crafted to make full use of the unique expression curves and modulation parameters. Onboard effects include reverb, delay, compressor, and EQ.
• Vast, Expandable Preset Library The platform now features 580 factory presets and up to 2048 preset slots for your own sounds, with a growing software ecosystem through partnerships with companies such as U-He, KiloHearts, Dawesome, AAS, and Synapse Audio.
• Standalone & MPE Controller Use it as a full standalone synthesizer without a computer, or as a powerful MPE/MIDI controller for external gear and software, with customizable aftertouch sensitivity profiles and response curves.
• Hands-On Interface Controls comprise 7 encoders, 9 buttons, pitch/modulation sliders, and a 4.3" color LCD, all in a sleek, minimalistic design.
• Thoughtful Connectivity Two ¼" pseudo-balanced line outputs handle full stereo playing, joined by a front-mounted ¼" TRS headphone port with volume control, USB-C, MIDI In and Out/Thru, and 2 pedal inputs.

Reviewing the launch, Synth Anatomy noted the Osmose features a novel keybed that breaks new ground, allowing users to manipulate and articulate sounds in a way never before possible with a traditional white/black keyboard — and that the 61-key version answers long-growing calls for a larger model with an extra octave for two-handed playing.
