About Control Surface Plug-ins

Supported control surfaces communicate with Logic Express via special plug-in files that are installed along with Logic Express. The plug-in files are located in the /Contents/MIDI Device Plug-ins subfolder of the Logic Express application bundle. To view the bundle contents, Control-click the Logic Express application icon, and choose Show Package Contents from the shortcut menu. Logic Express also checks for control surface plug-ins installed in the (optional) /Library/Application Support/MIDI Device Plug-ins and ~/Library/Application Support/MIDI Device Plug-ins (the “~” denotes your user home directory) folders.

When new control surface plug-ins are released independently of a Logic Express update (or supplied directly by the device manufacturer), place them in the folders described above (or as advised in the documentation supplied with the plug-in).
