If you use Ableton Live, you need a Launchpad. It displays your session view on 64 multicoloured pads, letting you launch multiple clips at once and control anything else in Live. It's an evolution in creating electronic music and this mini version does all the same cool stuff as the normal Launchpad. It's just as durable and gig-ready, the only difference is that it's even more portable and takes up less space in your bag or on your desk.
