Description

Step into a new dimension of musical expression with the Expressive E Osmose 61-key Polyphonic Synthesizer and MIDI Controller. This groundbreaking instrument redefines what it means to play synthesizers by integrating a 3D MPE keybed that responds to your every touch. Each key is a universe of its own, capable of detecting pressure, glide, and vibrato, which translate your intentions into sound with breathtaking accuracy. This unique keybed technology enables polyphonic aftertouch, allowing each finger to independently control vibrato, pitch, and dynamics, turning every chord into a nuanced symphony.

At the heart of the Osmose is the EaganMatrix sound engine, developed in collaboration with Haken Audio. This powerful engine offers a creative playground where physical modeling, FM, and subtractive synthesis meet. With over 580 factory presets and room for 2,048 user slots, you're equipped with an expansive palette to explore sonic horizons. The built-in effects—reverb, delay, compressor, and EQ—react in real time to your performance nuances, making every note a unique experience.

Designed not just to inspire, but to evolve with you, the Osmose is crafted in Europe with a commitment to quality and sustainability. It features comprehensive connectivity options including DIN and USB MIDI, and two continuous pedal inputs for further expression. With regular firmware updates, Osmose ensures that your instrument remains at the cutting edge of musical innovation.

Expressive E Osmose review | MusicRadar

musicradar.com

Expressive E's Osmose synthesizer and MIDI controller brings a highly innovative design to the table with its gesture-sensitive, semi-weighted keybed offering three-dimensional control. It's a powerful beast with its EagenMatrix synth engine, capable of producing a wide range of sounds. The transition from traditional keyboards is smooth, and the gestural control opens up a myriad of sound design possibilities. However, the synth editor can be daunting, and initial setup might deter some users. Additionally, a few bugs hint that Osmose isn't entirely the finished article. Despite these hurdles, it's a compelling instrument for expanding your sonic palette, especially for those seeking a future-proof synth/controller.

The Expressive E Osmose is hailed as a true game-changer, offering a unique take on keyboard design with its innovative three-dimensional control. The review praises its expressive capabilities, likening its tactile experience to playing a guitar or violin, though it acknowledges a learning curve for seasoned pianists. While the EaganMatrix engine offers rich sound possibilities, it comes with a steep learning curve. The build quality is praised, though minor gripes include the weight and some interface elements. Despite sound presets being hit-or-miss, the overall sentiment is highly positive, especially for those seeking groundbreaking expression in music production.

Expressive E Osmose review: A game-changing MPE keyboard, but a frustrating synthesizer

engadget.com

The Expressive E Osmose dazzles with its innovative keybed, offering unparalleled expressive control—ideal for those who crave tactile interaction. Its robust build and familiar keyboard layout make it approachable, especially for traditional pianists dabbling in MPE. However, its promise as a synthesizer is marred by the convoluted EaganMatrix engine, which feels more like a complex scientific endeavor than an intuitive musical tool. While it excels as an MPE controller, the synthesis side leaves much to be desired, with presets that often sound more like tech showcases than usable instruments. For those willing to navigate its complexities, the Osmose offers a unique but occasionally frustrating musical journey.
