Great Additions
Description
Building on the worldwide success of the 49-key Osmose, the new 61-key version adds an extra octave, giving musicians more room to explore, compose, and perform. Musicians can now choose between the original 49-key or 61-key model, depending on their needs and playing style.
Beyond the instrument itself, Osmose thrives within a living, evolving ecosystem of software, presets, and community-driven updates, ensuring it grows and improves over time. And with production now fully internalized in a new Polish factory, Expressive E guarantees the highest European quality standards for every instrument.
Osmose 61: A Bigger Range, Same Innovation
With 61 keys, Osmose 61 offers greater harmonic and melodic freedom, perfect for two-handed playing, complex arrangements, and live performance. It retains everything that made the 49-key model revolutionary: the expressive 3D keybed, MPE integration, high-end interface, and premium build quality - giving musicians the choice to stay with 49 keys or step up to 61.
Unmatched Expressivity
Developed and fully designed by Expressive E, the Osmose keybed sets a new benchmark for MPE instruments. Every note responds with nuance to velocity, press, aftertouch, pitch bend, pressure glide, strum, vibrato, and more - making the keyboard a natural extension of the player's hands.
Multi-Oscar-winning composer Hans Zimmer has already tapped into its expressive potential on landmark projects such as the Dune: Part Two soundtrack.
"You guys spent an enormous amount of time building exactly the instruments that should have been built a hundred years ago." - Hans Zimmer.
EaganMatrix Always at the Core of Osmose Sound
Powered by the legendary EaganMatrix engine, developed by Haken Audio, Osmose delivers rich acoustic textures and complex synth sounds that react intuitively to every gesture. Its versatile engine supports physical modeling, FM, subtractive synthesis, and more, complemented by onboard reverb, delay, compressor, and EQ.
With 580 factory presets and up to 2048 preset slots, Osmose offers a complete, performance-ready palette while staying true to the expressive soul of the instrument.
A Living Ecosystem
Osmose is more than an instrument; it is at the center of a living ecosystem that grows and evolves with its community of musicians.
Expressive E has expanded the software ecosystem around Osmose, offering a rich library of sounds through partnerships with renowned companies such as U-He, KiloHearts, Dawesome, AAS, and Synapse Audio. These collaborations are featured in the Expressive Suites, available on the Expressive E website.
Proprietary software explicitly designed for Osmose - such as the new Soliste (physically modeled solo strings) and Noisy 2 (a dual-layer, noise-driven synth) - has also been released to further expand musical possibilities.
This ecosystem is designed to grow. Expressive E is committed to making Osmose evolve over time, with regular firmware updates bringing smoother workflows, deeper DAW integration, and an ever more fluid user experience.
Coming soon, a series of mini-synths with intuitive editors for the EaganMatrix will make sound design more accessible than ever, transforming what was once a complex interface into an expressive, user-friendly platform for creativity.
Made in Europe: A New Factory in Poland
Until now, Osmose production has been outsourced to China. To meet global demand while guaranteeing uncompromising quality, Expressive E is taking a decisive step forward: a new assembly facility in Poland, fully dedicated to Osmose and future instruments.
For the first time, the company will no longer rely on subcontractors. Every stage, from design to assembly, will now be handled in-house. This shift gives Expressive E full control over the lifecycle of its products, ensuring reliability, sustainability, and the highest European quality standards.
It's an ambitious challenge for a young company, but one driven by passion, conviction, and a clear vision: to craft instruments that embody both innovation and integrity, from the very first design to the final note - and to gain even greater freedom to innovate.

Q & A

Protect your investment with the Long & McQuade Performance Warranty
A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.
Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.
How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
- Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
- Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
- No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
- Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
- Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
- Loaners Available: A loaner product may be given while the product is being repaired.
- Power Surge Protection: Your product is covered even if damaged from a power surge.
- Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
- Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.
Purchasing additional years of coverage
Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.
If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:
- NEW products: Starting at 4% of the current new selling price to double the warranty from 1 year to 2 years. Starting at 4% for each additional year.
- USED products: Starting at 4% of the current new selling price to increase the warranty from 3 months to 1 year. Starting at 4% for each additional year.
- GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
- BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
