The ESI Xkey 25 is an ultra-slim, lightweight, and portable 25-key USB MIDI keyboard designed for musicians, producers, and songwriters on the move. Crafted from robust, brushed aluminum, this controller offers full-sized, velocity-sensitive keys with polyphonic aftertouch—delivering an expressive and natural playing experience unlike most compact controllers.

Its smart keybed supports nuanced performance dynamics, while touch-sensitive pitch bend, modulation, and octave shift buttons give you intuitive control over your sound. Whether you're producing music on your laptop, triggering synths on your tablet, or composing scores in your DAW, the Xkey 25 delivers pro-level control in a portable format.
Class-compliant and USB-powered, the Xkey 25 requires no drivers and works seamlessly with Mac, Windows, iOS, and Android. It’s the ideal solution for producers, performers, and digital musicians who value form, function, and expressive playability.
