For your Inner DJ: Ultramixer is Linux Friendly

Both seasoned and fledgling DJ's can access spin software on Linux much more easily these days with Ultramixer. Programs like Audacity (Though with Ubuntu you'll want to run it from terminal with command: Aoss audacity) (Trust me), Sweep, and Ardour make audio editing/production possible, but Ultramixer makes it possible to DJ an event with your Ubuntu or Fedora Linux run PC.

Peep the features through their site. Very slick.
If you've used the program your thoughts are appreciated.
