Important Announcements for Upgrading from 2.0.x


For users upgrading from Mixxx 2.0.x or older, we have a few important announcements. First, if you are using Windows, you will have to uninstall any old versions of Mixxx before you can install 2.1.0 (unless you were using the 2.1.0 beta or release candidate). How to uninstall Mixxx varies on different versions of Windows:


  • Windows Vista, 7, and 8: Start > Control Panel > Programs > Uninstall a Program
  • Windows 10: Start > Control Panel > Programs > Programs And Features > look for Mixxx > Uninstall


If you are upgrading from Mixxx 2.0.0 or older and have MP3 files in your library, we have another important announcement. The good news is that we fixed a bug where the waveforms and audio playback of MP3 files were misaligned. The bad news is that we have no way of knowing which MP3 files were affected or how much the offset was. That means that waveforms, beatgrids, cues, and loops from older versions of Mixxx may be offset by an unknown amount for any MP3 file. Only MP3 files were affected by this bug; other audio file types are unaffected. You can either correct your beatgrids and cue points manually for each track, or you can clear this information for all MP3s and start fresh. Regardless, we recommend clearing the waveforms for all MP3 files. To clear these, type "location:mp3" into the library search bar, press Control + A to select all tracks, right click, and select the information you want to clear from the menu.

Want to help make Mixxx even more awesome?  The biggest thing we need is more people.  You do not need to be a programmer to help out. Giving feedback on the design of new features as they are being made is very valuable. Refer to the  Testing page on the wiki for more information on how to get involved with that. Reporting bugs and telling us your ideas on the  Launchpad bug tracker is a big help too! We cannot fix problems we do not know about, so please let us know if you find any issues with Mixxx. If you would like to help translate Mixxx into another language, refer to the  Internationalization wiki page. Of course, more programmers could always help! Read the  Developer Documentation on the wiki for tips on getting started contributing code to Mixxx.

We hope you have as much fun with Mixxx as we do!
