Apple Logic Pro 9 - Manual (Page 313)

Using Plug-ins from Other Manufacturers
Logic Pro can act as a host for (compliant, correctly installed and authorized) Audio Units
effect and instrument plug-ins from other manufacturers. Logic Pro can also control TDM
plug-ins when Pro Tools audio hardware is used. Details on the use of TDM plug-ins can
be found in the Logic Pro TDM Guide.
Important: Logic Pro cannot act as a host for plug-ins in VST or RTAS format. There are,
however, utilities such as the VST to Audio Units Adapter (http://www.fxpansion.com),
that “wrap” Mac OS X versions of VST plug-ins to create virtual Audio Units. Once wrapped,
most of these plug-ins behave, and can be used, just like Audio Units.
Loading Presets
Many plug-ins from other manufacturers use a proprietary storage format for their presets
(the equivalent of Logic Pro plug-in settings).
In most cases, a separate Preset (or similarly named) menu will be available in the plug-in
interface. Once loaded, you can save any of these presets as a Logic Pro setting.
In all cases, the global Compare, Copy, and Paste options of the plug-in window header
will work as they do with the native plug-ins of Logic Pro.
Working with the Audio Units Manager
Logic Pro uses the Apple AU Validation Tool to ensure that only plug-ins that fully comply
with the Audio Units specification are used in Logic Pro. This minimizes problems that
may be caused by third-party Audio Units plug-ins.
The validation process takes place automatically when:
• Logic Pro is first opened.
• An updated version of Logic Pro is installed.
• You install new Audio Units plug-ins, or update existing ones.
