This page lists the suggested projects for students working on Mixxx as part of Google Summer of Code 2011. Each of these projects represents something that we think would make a really big difference to our users and that we as a development team are really excited about. For advice on how to get in touch and how to apply, you should read gsocadvice.
The Mixxx Auto DJ mode is very simplistic – it mixes songs from the AutoDJ queue and crossfades them with a fixed overlap. This project aims to spruce up AutoDJ support to be much better. In particular, the fade-in and out points of songs should be configurable, as well as the crossfade length. More advanced use cases could
Many professional DJs must report the songs they play at gigs to an organization like ASCAP. Other DJs would simply benefit from the ability to look at their past DJ and see a history of the songs they played. This project aims to bring a Sessions or History feature to the Mixxx library. This feature would show a running history of every song the DJ played with Mixxx, grouped by “sessions” or times that Mixxx was run.
The Mixxx library search feature is fairly basic. It only searches for terms within the title, album, artist, genre tags. Furthermore, it is pretty slow because it is implemented as a SQLite LIKE comparison with every field it intends to search. We would like to drastically improve this by switching to a Full-Text-Search model such as that provided by Apache Lucene. For more information, see Wikipedia: Full Text Search. Beyond this, we would like to make library search box support advanced operators like searching on Google.
Here are some examples of queries we would like to support:
If you've used Mixxx, you know that our SYNC button does not work very well! All it does is match up the BPMs of the tracks that are being mixed. There is tons of room for improvement here. The goal of this project is to allow two decks to be synchronized such that they actively check whether they are in sync with the other, and make adjustments to stay in sync. Additionally, the creation of a master sync clock for decks to sync to would be great as well, because then the DJ could set the master clock at e.g. 130 BPM and all the songs they load would automatically sync to the tick of that clock.
Mixxx currently supports a wide-range of hardware MIDI controllers that DJs can use to perform with. Each supported MIDI controller has a “mapping” file that is bundled with Mixxx, but this mapping must be manually selected by the user before their controller works. The aim of this project is to increase the usability for new users by automatically selecting the correct MIDI mapping and to provide an intelligent workflow for when an unsupported MIDI device is connected.
This project will involve a lot of time thinking about use cases, dealing with users and understanding their requirements. It would be a great opportunity for a student to get involved with the Mixxx community. The student will also have the opportunity to borrow a MIDI controller from the development team for the duration of the project.
As always with Summer of Code, you aren't limited to the suggestions we've made here. If you've got a great idea for a project involving Mixxx then we're looking forward to hearing about it.
IMPORTANT: You should contact us first to get feedback if you're going to submit a proposal for your own project idea!
