What good is the greatest sound engine if its functions can't be controlled dynamically and intuitively while playing? Conventional keyboards with velocity and aftertouch offer too few options to achieve this, and their reliance on knobs, hand wheels, pedals, or breath controllers means too much attention is taken away from actually playing. This is exactly where the Expressive E Osmose comes in: Its innovative keyboard design unlocks new ways to control sound with gestures (press, bend, shake, and more) that bring a level of control usually associated with acoustic instruments. Each key has an extended range of motion from its usual resting point, which allows for additional per-note modulation whose range and target parameters can be modified with each patch and sound. Aftertouch sensitivity profiles and response curves can be customised for later use, with each of the advanced EganMatrix onboard sounds tailored for use with the unique expressive controls of the Osmose. This gives the term "expression" a whole new dimension for keyboard players.
The semi-weighted keys of the keybed are equipped with additional sensors that convert horizontal modulations and the position of the finger on the surface of the key into control signals. This allows for playing techniques such as shake, strum, and pressure glide that are otherwise not possible on conventional keyboards and means that pitch bend and dynamic sound changes can be generated simultaneously with the notes played. Aftertouch, pressure, and pitch bend can even be used polyphonically! The 24-voice sound engine is a version of Haken Audio's EaganMatrix specially adapted for the Osmose and can generate FM, virtual-analogue, or physical modelling sounds. The parameters of the Pitch Bend Slider and the Modulation Slider are programmed individually in each preset.
The Expressive E Osmose is aimed at experienced keyboardists who have reached the limits of their existing instrument. Supported by its advanced sound engine, the 3D keyboard opens up completely new modes of expressing musical ideas, and its dynamically playable tones can be used equally well for electronic music, Pop, Jazz, Fusion, or Hip Hop. Live on stage, keyboardists can play extremely expressive solos and in the studio, synthesizer parts can be worked on in unprecedented detail. The Osmose can also be used as a controller for other synthesizers and plug-ins.
Expressive E is a small and relatively young French manufacturer. Its flagship products are the Touché controller and the associated Lié software. Expressive E also makes a small series of plugins which emulate the physical vibrations of acoustic instruments, or model electronic circuitry. In addition, the manufacturer offers soundsets for various hardware and software synthesizers, most of which are free and designed to work in conjunction with the Touché controller.
With the Expressive E Osmose, experienced keyboardists can play highly expressive parts that rival the complexity and articulations of a virtuoso guitarist or passionate trumpeter. With the innovative 3D keyboard and flexible sound engine, keyboard passages on the Osmose can hold their own alongside acoustic instruments in a live performance without the need for additional equipment. While the Osmose requires a certain learning curve in order to master its unique capabilities, the ability to apply separate pitch bends or "pressure glide" with individual notes of a chord can elevate the interplay with other musicians to new heights. The Osmose can also be used as a MIDI controller in the studio, for example to play modern plugins that are designed for MPE and polyphonic aftertouch.
