We live in a wireless world—and now your keyboard controller can be wireless too. If you’re ready to cut the cord or step into the spotlight, the new MidAir 25 wireless USB MIDI controller is the answer you’ve been waiting for. We’ve taken all the functionality of the legendary Oxygen8 and packed it into a wireless controller that’s just as easy to use. Complete with 25 velocity-sensitive keys, eight MIDI-assignable knobs, mod and pitch bend wheels, assignable sustain button, three-digit LED display and more, the new MidAir 25 allows you to control soft synths, DAWs and standard MIDI instruments with the freedom of a wireless design. Powered via the included 9V power supply or standard batteries (also included), the MidAir 25 is the ultimate tool for both studio and stage. Item Box was previously opened in showroom.
