ESI Xkey 25 USB MIDI Controller

ESI Xkey 25 is an ultra-slim 25-key USB MIDI controller designed for mobile music production, home studios, arranging on the go and controlling software instruments. Its full-size keys retain the width of a traditional piano keyboard, while velocity sensitivity and polyphonic aftertouch provide expressive control over compatible virtual instruments.

The aluminium enclosure, 16 mm profile and USB bus-powered design make the Xkey 25 easy to carry. It connects via USB-C to Mac, Windows and compatible mobile devices and works with MIDI-enabled DAWs, virtual instruments, notation and learning software. Dedicated pressure-sensitive controls provide pitch bend, modulation, sustain and octave functions.

Why choose it? Xkey 25 combines full-size keys, a travel-friendly format and advanced polyphonic aftertouch. It is a practical controller for beatmakers, producers, composers and mobile-studio users.
