ESI XSynth

Your versatile partner in music production, always ready to go! - ESI Xsynth may look like a master keyboard, but it is much more: being a complete synthesizer, it is perfect for sketching ideas and turning them into reality — anytime, anywhere. Based on the acclaimed Xkey series, this portable synthesizer offers not only unmatched mobility but also an integrated MIDI and audio interface. Whether in the studio, on the road, or at home, Xsynth is the ideal solution for those who appreciate performance, flexibility, and elegant design.

Connectors
Xsynth is very slim yet has all the connectors you need.

Velocity-sensitive keys
Xsynth comes with 25 velocity-sensitive keys that exactly match the octave range of traditional pianos. Despite its slim design, they also offer polyphonic aftertouch.

Encoders and display
All functions and parameters of the synthesizer can be quickly accessed via encoders, with updates and real-time information on the Xsynth display.

Smart buttons
The durable rubber smart buttons provide functions such as Pitch Bend, Modulation, and Hold, allow octave range changes of the keyboard, Glide, and activation or deactivation of Xsynth's powerful built-in arpeggiator.
