Ableton Link integration for Pd. A sample app is here.

• Set up a libpd-based Xcode project as usual.
• Add the Link library and headers to your project setup as described here: http://ableton.github.io/linkkit/#getting-started
• Add pd_link_bridge/** to your header search path.
• Add pd_link_bridge/ios/PdLinkAudioUnit.{h,m} to the sources of your project.
• Add the Link preference pane to your user interface (e.g., by cargo-culting the relevant bits of the LinkHut sample project).
• Create a Link instance, a PdLinkAudioUnit instance, and a PdAudioController instance:

ABLLinkRef linkRef = ABLLinkNew(120, 4);
PdLinkAudioUnit pdAudioUnit = [[PdLinkAudioUnit alloc] initWithLinkRef:linkRef];
PdAudioContoller pd = [[PdAudioController alloc] initWithAudioUnit:pdAudioUnit];

• Create a Pd patch using the Link external, abl_link~. In order to create patches on a desktop computer (where the actual Link external is not (yet) available), you can use the mockups in pd_link_bridge/abstractions.
• Make sure to check out the help patch of abl_link~.
