Expressive E Osmose 61

The Expressive E Osmose 61 is a five-octave advanced MPE synthesiser and performance keyboard that combines a cutting-edge 3D keybed with the Haken Audio EaganMatrix synthesis engine for unrivalled expressive control in a fully standalone instrument.

Extended Five-Octave Range

Expressive E evolves the award-winning original design into a 61-key format, enabling extended two-handed playing, complex harmonic structures and fluid performance techniques that suit advanced composition, studio work and live performance. This larger keybed expands the expressive range without altering the core feel or sensitivity that defined the 49-key version.

Next-Generation Expressive Keybed

The proprietary three-dimensional keybed senses vertical movement, lateral pitch gestures and continuous pressure per key, so players shape pitch, timbre and dynamics directly with their fingertips. Each gesture responds instantly and independently, creating a level of articulation that surpasses standard MPE-compatible keyboards by making multidimensional control its native foundation rather than an add-on.

EaganMatrix Sound Engine

The powerful onboard Haken EaganMatrix engine supports physical modelling, additive synthesis, FM, modal and hybrid structures, offering immense sonic depth for sound designers and performers. Users access over 500 factory presets with capacity for up to 2048, while the integrated colour display and dedicated controls allow deep programming without relying on a computer.

Studio and Stage Ready

Balanced line outputs ensure professional audio connection, while USB and DIN MIDI integrate seamlessly with hardware rigs and DAW-based workflows. Two pedal inputs expand performance control and a dedicated wheeled soft case will provide premium mobile protection. Expressive E now manufactures the Osmose series in its European facility, ensuring consistent build quality and long-term platform stability.
