Development Roadmap

This page represents the opinion of the Mixxx development team, as such it is not editable by general users. If you have comments or suggestions, please contact us.

Main Design Principles

These are some core goals which are critical for Mixxx to become a world-class application, somewhat in order of importance:

Stability - Having a stable platform for DJs to work from is key
Performance - Optimize latency over throughput
Support a good level of latency for as many configurations as possible
Usability - Most functions must be bonehead-easy to use. The manual must not be required reading!
Good hardware support
For as many devices as possible
With easiest possible setup
Support all likely input formats
Features
Should be guided by feedback from DJs
Great care should be taken to ensure that stability is not compromised by new features
Mixxx doesn't need to make the coffee, features should demonstrably improve the user experience

Release Schedule

1.7.3

Bug-fix release. See https://launchpad.net/mixxx/+milestone/1.7.3 May be bumped by 1.8.0 release.

1.8.0

// Release Schedule //

Nov 16 2009 -- Feature Freeze
Feb 5 2010 -- private(-ish) beta testing
Feb 15 2010 -- Mixxx 1.8.0 Beta 1
May-July -- Mixxx 1.8.0 Beta 2
??? - Mixxx 1.8.0 Final

We tried to sync up with the Ubuntu release cycle, but were unable to commit enough developer time to fixing bugs, despite our best efforts. (Feature freeze for Lucid Lynx was February 18th, 2010.)

To-do list

New main features:

Looping
New Library
Ramping Pitchbend
Multiple MIDI device support
~~Shoutcast~~
M4A support

Side Projects

Build Server!
Test Evangelism
SConscript Refactor

Bugs fixed: https://bugs.launchpad.net/mixxx/+milestone/1.8.0

1.9.0

Release Date: Late-2010/Early-2011

No firm roadmap beyond 1.8.x as yet, will be decided once 1.8.0 cycle is complete.

Ideas for possible improvements include:

SSE Enhanced Engine
Script Timing
Finish LADSPA effects
DVS mode
n-Deck
External Mixer Mode
Incremental Library Enhancements (e.g. inline track previews)

Probably Longer Term

To add to the list of ideas that would be cool in Mixxx, add them to feature_discussion or file a Wishlist bug at Launchpad.

Some reasonably sensible sample of wishlist ideas for new features:

Skinning Engine
Revamped Control System
Internationalization
Macro/script playback
Sampler
Inline track previews
Better BPM detection
