Built around the custom Augmented Keyboard Action, Osmose connects every gesture - press, bend, shake or strum - to sound with uncanny responsiveness. Its extended polyphonic pressure, high-resolution aftertouch, and individual pitch control offer a playing experience closer to an acoustic instrument than a typical synth.
