The M-Audio Keystation 49 MK3 is a MIDI keyboard controller designed for sequencing music and playing virtual instruments on a Mac or Windows computer. It is also compatible with iOS devices. The Keystation 49 MK3 features 49 full-size velocity-sensitive keys and a series of controls that expand the range of playable notes, while also providing expressive capabilities.
Assignable transport and directional controls allow for playing, performing, and recording with music software without using a mouse or trackpad. If you've got your own sustain pedal, you can plug it in via the 1/4" sustain pedal input. Lightweight and durable, the controller is USB-powered, class-compliant, and supports USB-MIDI connectivity. Additionally, the unit supports iOS connectivity using the Apple iPad Camera Connection Kit (available separately), enabling you to perform and compose with audio apps on an iPad or another iOS device.
The 49 MK3 comes with a variety of software, including DAWs such as Pro Tools | First M-Audio Edition and Ableton Live Lite. Also included is AIR Music Technology Xpand!2, a multitimbral all-in-one synthesizer which houses up to four sounds to help you create your own unique VI patches.
Keyboard sounds can be achieved via three included AIR Music Technology soft-synths: The Mini Grand, with seven acoustic piano sounds, and the Velvet, which gives you five vintage electric piano sounds. Additional software includes Skoove and Melodics. You also get 2GB of Touch Loops material to foster your creativity. The keyboard comes with a USB Type-A to USB Type-B cable.
