From Our Research Team:

Ultra-Thin, Ultra-Versatile MIDI Controller!

Take the M-Audio O2 25-key ultra-thin USB MIDI controller anywhere you want to make music! Small enough to fit in a bag along with your laptop, the slim-line O2 is perfect for throwing down bass lines, programming drum patterns, triggering effects and tweaking virtual studio parameters - anywhere, anytime.

M-Audio O2 Mobile USB MIDI Controller at a Glance:
  • Compact controller for any soft synth or DAW software, with setup memory and editing software
  • 25 full-size touch-sensitive keys plus 18 assignable MIDI controllers
  • Built-in MIDI interface plus USB MIDI I/O for computer connection
  • Includes Ableton Live Lite Software

Compact controller for any soft synth or DAW software
The O2 follows in the footsteps of M-Audio's Oxygen8 - one of the very first mobile MIDI controllers. The ultra-thin O2 is perfect for laptop-based recording systems or control of MIDI synth modules. It's easy to assign controllers to match your soft synth or DAW software. Plus, the O2 has 5 internal setup locations so you can switch from application to application. It also integrates with Enigma editor/librarian software (a FREE download for registered owners) for unlimited setup creation and storage.

25 full-size touch-sensitive keys plus 18 assignable MIDI controllers
The secret to the O2's thin profile is its 25 full-width, half-action keys that only need half the vertical space of most keyboards. With octave shift buttons and pitch bend and modulation controls, you can perform on the O2 just as you would on a full-sized keyboard controller. Plus, the O2 has 8 fully assignable MIDI knobs, 8 assignable buttons and a volume slider that can be assigned to perform other MIDI functions. Using an Advanced Function button, you can also activate 12 additional functions from the keyboard. And a rear-panel sustain pedal jack gives you even more performance control.

Built-in MIDI interface plus USB MIDI I/O for computer connection
You can use the O2 to connect to a MIDI module and your computer at the same time. A built-in MIDI Out port can transmit performance data to your external sound module, while the USB MIDI I/O provides an interface with computer sequencing and recording software. The O2 even includes Panic and Controller Mute buttons for instant cutoff of stuck notes or silencing your O2 during breaks. This tiny controller packs a big MIDI punch!

Includes Ableton Live Lite Software
To get you started making music with your O2 right away, M-Audio includes a copy of Ableton Live Lite software for mixing samples and loops within one easy-to-navigate interface. With your O2 and Live Lite you'll be making tracks within minutes of opening the box!

The rotary encoders are a really useful feature when I am adjusting parameters in my soft synths. This thing is really portable too. The keys are real slim and not meaning width wise but height wise, so it fits nice into a backpack. There really is something nice about these keys especially for certain synths that I have, they just respond nicely when playing. close [-]

From the customer service call after my order, to e-mailing me a copy of the invoice, to the great price, free shipping and candy in the box...a pleasure!
