On top of all that, it's got high-quality knobs and sliders (they don't feel cheap!), an X-Y trackpad, SPDIF digital output, and a mod joystick that can be set to springloaded return (like a Korg or Roland) or not (like a traditional mod wheel). It can be powered by USB, the included external power supply, or batteries that can be recharged over USB. And unlike most controllers in this price range, its wonderful-feeling semi-weighted keyboard is pressure-sensitive."
