Development Roadmap

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
• Mar 2010 -- Mixxx 1.8.0 Final

We're trying to sync up with the Ubuntu release cycle. Feature freeze for Lucid Lynx is February 18th, 2010.

To-do list

New main features:

• Looping
• New Library
• True 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
