Cotracks is a new iPad app that brings serious jambox design to the tablet PC format. The morphable 1-player/2-player/4-player layout, and the intuitive drag-and-drop interface are great examples of what touch-screens can do so well. I’m excited that a company like Futucraft has finally brought such musicality and true collaborative play to their virtual jambox. Commenters inform me that Rockmate is another jambox iPad app worth checking out.
