Development Roadmap

These are some core goals which would seem to be critical for Mixxx, somewhat in order of importance:

• Stability
  • Having a stable platform for DJs to work from is key
• Good hardware support
  • For as many devices as possible
  • With easiest possible setup
• Support a good level of latency for as many configurations as possible
• 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

Depending on developer time, we may backport some bugfixes to 1.5.0 and do a maintenance release of the 1.5 series while 1.6.0 is becoming stable.

This will be the next feature release and will include (hopefully) all the stuff in the changelog below. Fast pace of development has meant lots of work originally slated for 1.7 will make it into this release. The huge number of new features mean it will probably stay in beta for several months. In addition to the features in the changelog, it will hopefully also have:

• More hardware controller support
• Build system moved to scons
• Vinyl control
• Anything else exciting we have time for…

• Fix critical bugs: https://bugs.launchpad.net/mixxx/1.6/+bugs

This will be the feature release following 1.6.0 and will probably go into beta some time in 2008. No fixed plans this far into the future but rough targets are:

• Macro/script playback
• Sampler
• Internationalization?

Since Mixxx 1.5.0 was released (March 4th, 2007), the following changes have been made:

• New MIDI mappings for Tascam US-428, M-Audio X-Session Pro, Evolution X-Session, FaderFox DJ2, and the M-Audio Torq Xponent

• Hercules support on Linux improved (jog wheels work again)
• New nCut skin from Frank Willascheck
• (Trancer skin?)
• Big stability improvements (3 bug fixes)
• Multiple soundcards can now be used for output (master/headphones), in case you don't have a soundcard with 4 outputs on it.
• Adam's wicked colour scheme support for skins
• Can now change skins without restarting Mixxx (more hard work from Adam)
• Channel VU meters are now pre-fader
• VU meters are now much more smooth

• Starts in fullscreen mode if launched with the -f flag.
