Put custom mappings that you made or downloaded from the forum in the following folder. The MIDI Learning Wizard puts its mapping files here:

• GNU/Linux: /home/<username>/.mixxx/controllers
• OS X: /Users/<username>/Library/Application Support/Mixxx/controllers
• Windows: C:\Users\<username>\AppData\local\Mixxx\controllers. On Windows XP, replace Users with Documents and Settings. The %USERPROFILE%\AppData folder is hidden, so if you have not already, you will need to set Windows explorer to show hidden files and folders.

The default mapping files, which you can look at for examples or a starting point for your own custom mapping, are located in the following directory:

• GNU/Linux: /usr/share/mixxx/controllers or /usr/local/share/mixxx/controllers
• OS X: /Applications/Mixxx.app/Contents/Resources/controllers/
• Windows: C:\Program Files\Mixxx\controllers
