Jonas Norberg, CEO and Pacemaker, gave a sneak peak of at their upcoming app for the BlackBerry PlayBook during the keynote general session at BlackBerry World this morning. The app will allow you to mix, sync, and scratch digital music on your BlackBerry PlayBook, as well as apply effects, loop, and much more to provide a rich DJ experience. Jonas stated that they were looking for a mobile platform to create an app for, and after much investigation they chose the PlayBook for its QNX OS, as it's the only "true, real-time operating system" on a mobile device. Can't wait for Pacemaker to launch; it looks amazing!
