Osmose Keyboard Synthesizer + MPE MIDI Controller

Imagine a keyboard where every key tilts, shakes, and responds like a living thing, turning your wildest playing ideas into sound without missing a beat. That's the magic at the heart of this instrument, born from Expressive E's obsession with making electronic synths feel as alive as an acoustic guitar or violin.

Its 49 full-size keys pack three-axis control via the custom Augmented Keyboard Action, capturing tap for velocity, press for dynamics, polyphonic aftertouch, side-to-side pitch bends for vibrato, pressure glides for seamless portamento, even strum and note-off gestures, all feeding into the EaganMatrix engine by Haken Audio. This modular powerhouse blends physical modeling, FM, additive, spectral, and virtual analog synthesis across 5 oscillators per voice, up to 24-voice polyphony, multimode filters, and effects like reverb, delay, compressor, drive, EQ, plus newer additions such as tanh saturation and long reverb. A color LCD, 6 encoders, pitch/mod sliders, octave buttons, and expressive arpeggiator make tweaking intuitive, whether standalone or as an MPE MIDI controller with USB/DIN I/O, pedal inputs, and 2x 1/4" TRS outs plus headphone jack. At 894 x 316 x 87.5 mm and 8.3 kg, it's a premium, roadworthy build with 580 factory presets and 2048 slots, editable via companion software.

Players love how it unlocks organic expression that traditional boards can't touch, with sounds evolving fluidly to your touch—though some note a learning curve to master the gestures, it's hooked those craving deeper control in studios and on stage.
