Product Description
The Expressive E Osmose 61 takes expressive performance to new heights, building on the success of the original 49-key model. Now offering an extended 61-key range, it provides greater harmonic and melodic freedom for both composition and live performance. With its pioneering 3D keybed, powered by the acclaimed EaganMatrix sound engine, every note comes alive through touch, pressure, and movement, transforming the way musicians interact with sound. Crafted in Expressive E’s new European facility in Poland, the Osmose 61 delivers the finest build quality alongside cutting-edge innovation. The instrument sits at the centre of a constantly evolving ecosystem, enriched with new software, presets, and collaborative expansions from leading developers. Whether in the studio or on stage, the Osmose 61 offers limitless expression and a deeply tactile playing experience that blurs the line between acoustic and electronic performance.
Features
- Expanded 61-Key Expressive Keybed:
Offers a wider playing range for two-handed performance, while retaining the same groundbreaking three-dimensional touch response as the original Osmose 49. - EaganMatrix Sound Engine:
Delivers versatile synthesis including physical modelling, FM and subtractive methods, ensuring dynamic, expressive sounds that respond intuitively to every gesture. - European Craftsmanship:
Built in Expressive E’s new Polish factory, ensuring superior manufacturing quality, reliability and sustainability throughout the production process.
Unmatched Expressivity:
At the heart of the Osmose 61 lies its expressive keybed, designed to react to even the most subtle gestures. Each key senses velocity, pressure, pitch bend, and vibrato, making the instrument feel alive under your fingertips. It bridges the gap between keyboard and acoustic performance, enabling nuanced phrasing and dynamic control that inspire creativity. Trusted by professionals such as Hans Zimmer, it offers a truly musical experience where sound naturally follows movement, emotion, and intent.
Evolving Sound Ecosystem:
The Osmose 61 is part of an expanding software and sound ecosystem that grows with its community. Expressive E continually releases new instruments and updates, including Soliste and Noisy 2, alongside collaborations with renowned developers such as U-He and AAS. These updates ensure the instrument remains fresh and versatile, while future editor tools will make the powerful EaganMatrix engine even more accessible to sound designers and performers alike.
Made in Europe with Vision:
With production now fully internalised in a new Polish facility, Expressive E has taken complete control of its manufacturing process. This ensures the highest European quality standards, while supporting a sustainable, transparent production model. From design to assembly, every Osmose 61 is crafted with precision and care, reflecting the company’s vision of blending innovation with craftsmanship. The result is an instrument built to inspire, endure, and evolve for years to come.
