The AudioUnit node hosts an AudioUnit plug-in. Double-click to open the AudioUnit's view. Many AudioUnit plugins are available for purchase online.
Some AudioUnits are not compatible with Mac App Store apps. If the AudioUnit node shows "Error: see documentation" then download the "unsandboxed" version of Audulus, here. This version requres the Mac App Store version of Audulus to be installed, but doesn't run with the same restrictions. If the unsandboxed version does not fix the error, please contact support.
We plan to implement AudioUnit parameter control via additional node inputs in a future version.
