* Our DJ system is an open source ( http://www.brighthub.com/computing/linux/articles/62137.aspx ) program called Mixxx. Mixxx is the equivalent of a turntable. Mixxx allows you to queue up a current track and a reserve track, cross-fade between the two tracks, do a number of sound effects, create a playlist, and speak on the air. Mixxx has a lot of music available in its library. The music in its library comes from our audio server (where all of the shared music of sudo room lives). (We encourage you to add music to our audio server! Check out the instructions for adding music to the audio server: https://sudoroom.org/wiki/File_server)

* When you start Mixxx, it will take its sweet time to scan our server and import everything into its library.
* When you start Mixxx, it will take its sweet time to scan our server and import everything into its library.
* As it’s doing that, you can add things from the library (the list of songs at the bottom of the screen) to the left slot and the right slot. To add tracks, right click on them and select "Load to Deck 1" (for the left) and "Load to Deck 2" for the right. Loading to the deck only queues the song up, but doesn’t play it. In order to play a song on either side, hit the play button for the side that you want to play (the play button is right by the CUE button). For more info (or if the above instructions are totally confusing), check out this basic tutorial for Mixxx: http://www.youtube.com/watch?v=g8ezCqolx04.

* You can use the physical mixer to crossfade between your own computer/music player plugged into channel 2 and the computer that’s plugged into channel 1!

* Even more fun times: Mixxx itself is a digital version of the physical mixer and allows you to have 2 pieces of music queued up that you can switch between (the crossfader on Mixxx is in the middle of the screen). So technically you can crossfade between three different things: whatever you have on your own computer/music player, and the two tracks you can queue in Mixxx. Wow, a world of possibility awaits you.
