Free yourself from the confines of cables with the Korg microKEY Air 61. Although you can connect via USB with the microKEY Air 61, this controller's most impressive feature is its 30 hours of wireless control using Bluetooth and a pair of AA batteries. The intuitive controls on the Air 61 include separate pitch and mod wheels as well as octave selection buttons and even an input for a sustain pedal, making controlling your virtual instruments or working in a DAW an absolute breeze, and you have tons of room to work with this MIDI controller's 61 velocity-sensitive keys.
