M-Audio has announced the KeyRig 25 keyboard controller and software bundle, which closely follows the release of the previously announced KeyRig 49 package. Each include a keyboard controller plus M-Audio’s Key Rig software (PC only). The KeyRig 25 controller is designed to fit into a backpack along with a laptop computer to form a powerful mobile studio.

The KeyRig 25 features an ultra-slim, 25-note keyboard with half-depth action, along with eight MIDI-assignable knobs and buttons. The KeyRig 49 features a 49-note, synth-action keyboard designed for users who want a more traditional approach to keyboard playing.

Both keyboards include professional pitch bend and modulation controls, an assignable volume slider, octave +/- buttons and sustain pedal input. The units are powered from the computer via a single USB cable and work right out of the box with Windows XP and Mac OS X systems—no driver installation needed.

Both keyboards are currently shipping. Each keyboard carries a US MSRP of $129.95.

Both configurations feature M-Audio’s Key Rig software (valued at $129). Compatible with most PC environments, Key Rig delivers four modules for stand-alone or plug-in use: SP-1 Stage Piano, MS-2 Polyphonic Synthesizer, MB-3 Tone Wheel Organ and GM-4 General MIDI Module. The master section allows users to route, split, layer and mix these four powerful modules in whatever way best suits their performance and recording needs. A master effects section also provides for adding a common effect in addition to the individual effect section included with each instrument.

“The KeyRig 25 offers a familiar form factor similar to our ground-breaking Oxygen 8 keyboard, while the KeyRig 49 continues on the path of our best-selling Keystation 49e. The addition of the Key Rig software bundle makes these offerings even more powerful for PC users,” said Adam Castillo, marketing director at M-Audio.
