Apple Logic Express 9 - Manual (Page 309)

Important: Logic Express 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 Express 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 Express 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 Express.
Working with the Audio Units Manager
Logic Express uses the Apple AU Validation Tool to ensure that only plug-ins that fully
comply with the Audio Units specification are used in Logic Express. This minimizes
problems that may be caused by third-party Audio Units plug-ins.
The validation process takes place automatically when:
• Logic Express is first opened.
• An updated version of Logic Express is installed.
• You install new Audio Units plug-ins, or update existing ones.
