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. 25 full-size, half-action, velocity-sensitive keys. There are 8 knobs and 8 buttons, all fully assignable. Other realtime controls like the assignable volume slider add to the performance and programming capabilities. One simple USB connection serves as both a MIDI interface and bus power source. Class compliancy with Windows XP and Mac OS X means you can get down to business without installing any drivers.
