Meet the Xkey Air: a musical instrument that pairs with your mobile device to help you play and practice your music on the go. You will be able to use this keyboard with your favorite apps such as GarageBand and Pro Tools. The Xkey Air 25 has a more compact design, while you can use the Xkey Air 37 in your studio.
These keyboards have an aluminum case and a long battery life. You can use the companion app to configure your instrument how you like. You get fully programmable smart buttons as well. Yet another interesting Indiegogo project.
