Student Project Ideas for Google Summer of Code 2011

This page lists the suggested projects for students working on Mixxx as part of Google Summer of Code 2012. 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.

Synchronization Improvements

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.

Minimum Deliverables

• Implement a master-clock in the Mixxx engine
• The master clock will have a BPM that it "beats" at.
• Implement synchronization of decks to the master clock signals.
• Synchronization in this case is:

    * Adjusting the rate of each deck to match the master clock
    * Adjusting the "phase" or the alignment of the deck so that the beats of the deck line up with the beats of the master clock. 
* Create GUI widgets to control the master clock and assign a deck to synchronize to the master clock.
* Allow a deck to be set as the "master" deck 
* This is more open-ended -- think about the different ways to implement this and talk about it in your proposal.
* Bonus: Implement a metronome feature that ticks to the beat of the clock.

Plug and Play MIDI Mode / Community MIDI Mappings

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.

Minimum Deliverables

• Implement auto-selection of MIDI mappings based on connected MIDI devices.
• For unsupported devices, implement a UI and simple server-side functionality to:
  1. Check mixxx.org for additional community-provided mappings.
  2. Allow ratings and comments to be made on community-provided mappings.
  3. Allow user-created mappings to be uploaded to mixxx.org.

Enhanced Platform Integration

As a cross-platform application, Mixxx runs on Windows, Mac OS X, and Linux....

Something Else!

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!

Minimum Deliverables

• Something awesome. We will work with you to define the deliverables.
