Mixxx User Manual: Hardware Setup.

This chapter describes the most common hardware setups to serve as examples. We will go over the setup of timecode records/CDs, MIDI control and keyboard control.

Audio Output.

Headphone cueing, or just cueing, is previewing the next track you would like to mix in your headphones. The audience will not hear what you are cueing in your headphones. Being able to cue is a crucial aspect of DJing.

In order to cue with your computer, you will need at least 2 separate audio outputs. Traditionally, a headphone jack on most laptops is not a second audio output. Rather, plugging headphones into the jack simply redirects the laptop’s main output to your headphones. Having a headphone jack alone will not allow you to cue.

Common Configurations.

Unlike some commercial DJ systems, Mixxx can control multiple audio devices simultaneously. Depending on your budget and application area your sound setup and requirements may vary. This section provides useful information for club, hobby and radio DJs alike.

Laptop Only.


Mixxx User Manual: Installation.

Mixxx is free mixing software for DJs, providing everything needed to create live mixes.

It allows you to beatmatch songs and crossfade them together, like you would with turntables and a mixer.

Installation on GNU/Linux.

Official packages of Mixxx are only offered for Ubuntu Linux. However, Mixxx can build on almost any Linux distribution.

Installation on Ubuntu.

Method A: Personal Package Archive (ppa)

  • Open a terminal and type the following commands. Type in your administrator password if asked for.

sudo apt-add-repository ppa:mixxx
sudo apt-get update
sudo apt-get install libportaudio2 mixxx

  • Start Mixxx by simply typing mixxx into the terminal, then hit Return .

Method B: The Ubuntu Software Center.


Mixxx User Manual: Introduction.

Mixxx allows you to perform live DJ mixes with your digital music collection. It helps you rock the party with MIDI controllers, vinyl turntables, or even just your keyboard.

Mixxx gives you everything you need to become a professional DJ (except talent and hard work).

Using Mixxx, you can rock the party with your vinyl turntables, your MIDI/HID controllers, or even just your keyboard.

Mixxx is used by professional DJs and bedroom DJs alike.

It is designed by an international team of volunteer DJs who want to bring the joy of DJing to everyone.

The project is non-profit, open-source and community driven. Together and with your help we aim to build the best DJ software ever created.

The project was started in early 2001 for a doctoral thesis as one of the first digital DJing systems.

Today it is a polished application that is downloaded over one million times annually and includes many features common to digital DJ solutions as well as some unique ones: It natively supports advanced MIDI and HID DJ controllers, is licensed under the GPL (v2.0 or later) and runs on all major desktop operating systems.

As of Mixxx 1.10.0, over 100 developers and artists have helped create Mixxx.

giFT plugin for Ares P2P network.

giFT-Ares is a plugin for giFT that connects to the Ares peer-to-peer filesharing network. Here you can find last (2010.11.23) working packages for Ubuntu GNU/Linux distributions.

giFT filesharing system is a modular daemon capable of abstracting the communication between the end user and specific filesharing protocols (peer-to-peer or otherwise). The giFT project differs from many other similar projects in that it is a distribution of a standalone platform-independent daemon, a library for client/frontend development, and modules for their own homegrown network, OpenFT, as well as the existing Gnutella network.

Apollon is a graphical frontend (KDE-based) to the giFT file-sharing system. It allows the user to perform searches and control downloads and uploads. Apollon needs a giFT daemon to be useful.

Apollon has many fine features such as file preview, multi-tabbed searching, filtering of search results, docking in the KDE/GNOME system tray, and downloading of entire remote directories.

Here we provide last packages from old Ubuntu versions.

Convert Audio / Video Files With Selene Media Encoder.

Selene is an audio/video converter for converting files to OGG/OGV/ MKV/MP4/WEBM/OPUS/AAC/FLAC/MP3/WAV formats.

It aims to provide a simple GUI for converting files to popular formats along with powerful command-line options for automated/unattended encoding.


  • Encode videos to MKV/MP4/OGV/WEBM formats.
  • Encode music to MP3/AAC/OGG/OPUS/FLAC/WAV formats.
  • Option to pause/resume encoding
  • Option to run in background and shutdown PC after encoding
  • Bash scripts can be written to control the encoding process
  • Commandline interface for unattended/automated encoding

Selene is an audio/video converter for Linux that uses bash scripts for transcoding the input files. The scripts can use any command line utility for encoding the input and Selene will display the progress along with options to pause/resume/shutdown, etc.

Since the conversion process is driven by bash scripts, this makes Selene extremely flexible. Bash scripts can be written for a wide variety of transcoding tasks.

Custom Stellarium Landscapes.

After my first successful try today, I thought I'd write a little tutorial for creating landscapes. Here are some (hopefully) simple steps:

1. Take your images. All I did was take my compact camera and my tripod out to my desired location, and take a set of horizon shots (all the way round) and then import them to Autostitch to make a simple panorama (see below). I filled the ground in by copying and pasting, as you can see (the original panorama was not straight, so it left some black areas underneath).
The Panorama must be a PNG, and I recommend sizing it down to about 2048 pixels in width. The following panorama has already been processed for Stellarium (see step 3) which is why the sky is missing. Once you have your panorama, move on to step 2. 

2. Extend the canvas. This involves increasing the height of the image above and below the horizon, as shown in the illustration below. This is important because otherwise the horizon will be too 'thin' and it means that you have to zoom out too much for the scenery to be properly sized.

Stellarium Landscapes: South America, Polar regions and Special.

Creating a Personalised Landscape for Stellarium.

Digital cameras are easy and cheaply available these days so whatever you have should do.

One mega-pixel resolution is quite sufficient.

The camera needs to be mounted on a tripod so that reasonably orientated pictures can be taken.

Select a time of day that is quite bright with a neutral cloudy sky so there will be no shadows and a sky of the same overall texture.

This will make it easier to remove later.

The pictures were all saved in the JPG format which was used as the common format for all processes up to the removal of the background.

With a camera that takes 4:3 ratio pictures I found 14 evenly spaced pictures gave the best 360° panorama in the program I used to produce it.

Stellarium Landscapes: North America.

dAfter my first successful try today, I thought I'd write a little tutorial for creating landscapes. Here are some (hopefully) simple steps:

5. Write your landscape file. This can be done by copying and editing the following text into your 'landscape.ini' file:
name = Enter your landscape name here
author = Enter your name here
description = Enter a description here
type = spherical
maptex = yourimagename.png
angle_rotatez = Enter angle
planet = Enter planet
latitude = +XXdXX'XX"
longitude = -XXdXX'XX"W
altitude = X
name: This is the name of your landscape as it will appear in the program.
author: Your name
description: A brief description of the landscape.
type: The style of image. Leave as spherical.
maptex: The filename of your panorama (in the same folder as the .ini file).
angle_rotatez: Experiment with this to get your compass points in the right location. It is a three figure bearing (i.e. - 010, 254, etc...)
planet: The name of the planet your landscape is on.
latitude/longitude: The location of your landscape on your planet. Does not need to be accurate - it is for reference purposes only. It will not affect what you see in the sky.
altitude: The altitude (M) of your spot. Once again, purely for reference.
