Expressive E Osmose – Next-Generation Synthesizer
The Expressive E Osmose is a groundbreaking synthesizer that combines MPE technology with a unique 3D expressive keyboard (A.K.A.). This allows the user to control each note individually, enabling unparalleled expressiveness and natural playing. The unit is powered by the EaganMatrix sound engine from Haken Audio, offering multiple types of synthesis, including FM, physical modeling, and granular. Osmose works both as a standalone instrument and as a MIDI/MPE controller for studio and stage. Its ergonomic interface with a color LCD screen and intuitive encoders allows fast and smooth sound manipulation without the need for a computer.
