The Novation SL Mk ii 49 is an awesome addition to any studio, project or otherwise. This controller will give you a hands on approach to your music production. Keeping the awesome 49-key semi weighted keybed aside, it features 8-trigger pads, 8 sliders, 32 multi-use buttons, 8 encoders, 8 pots, Xpression pad and Xpression port. The features could go on and on. To make sure you can get the USB powered SL Mk ii running quick, it comes with Ableton Live 7 Lite and Automap 3 PRO software to make the process of assigning controls a breeze. As a final thought, the SL Mk ii is also a fully functional control surface for your DAW. When I record in my home, I am not always next to my computer so the transport controls are a life-saver. There are many USB MIDI Controllers out there but consider the features they offer and you find yourself begging for the Novation SL Mkii 49.
