- Xcode 4.6 or later
- Max 6.1 or later
- Download the “Audio Tools for Xcode” package by going to Xcode > Open Developer Tool > More Developer Tools ...
- Install the CoreAudio folder found in the “Audio Tools for Xcode” package. Make sure to grab the one from Feb. 16, 2012. The Xcode packages assume it’s in the folder /Applications/Developer. If you install it somewhere else, change the CORE_AUDIO_LOCATION setting in the Xcode projects
Building an AudioUnit
- Duplicate the provided MyAU project with the command: python duplicate.py MyAU <My Plugin Name> <My Company Name> (For example: python duplicate.py MyAU YourAU MyCompany)
- Open a gen~ patch to be turned into a plugin.
- Send gen~ the exportcode message in order to export the genpatcher as C++ code.
- Open the Xcode project generated in step 2.
- Change the COMP_MANUF [must be 4 letters] and COMP_SUBTYPE settings in the <My Plugin Name>.r resource file and the <My Plugin Name>-Info.plist file.
- If you installed CoreAudio in a location other than /Applications/Developer, change the CORE_AUDIO_LOCATION build setting to the appropriate location and change the location of all of the files in the CoreAudio folder so that Xcode can compile them.
- Click on the project in the Project Navigator to show the build settings
- Click on the <My Plugin Name> target under the Targets section
- If not already showing, click on the Build Settings tab
- Under the User-Defined section, see the CORE_AUDIO_LOCATION setting to be changed (you can use the search field in the Build Settings to quickly locate it)
- Build the project.
- Copy the build product to the /Library/Audio/Plug-Ins/Components folder.
- Run auval -a to verify that the plugin functions properly.
