In concert with its release of Logic Pro 9.1, Apple has released Main Stage 2.1, updating the live performance program that's part of Logic Studio with a long list of improvements. The main changes include added support for 64-bit mode, added compatibility with 64-bit Audio Unit plug-ins, reliable syncing for Multiple Playback plug-ins that are grouped together, increased compatibility with documents created in Main Stage 1.x, and improved recording with the Loopback plug-in. Also, two crashing bugs have been fixed, including one that was triggered by using Command-N to create a new concert when a Save dialog for a previous concert was still open, and another that occurred occasionally when closing or quitting the program. A full list of mostly minor changes is available on Apple's Web Site. Running the program in 32-bit mode requires Mac OS X 10.5.7 or later; 64-bit mode requires Mac OS X 10.6.2 or later. The update is available via Software Update or the Apple Support Downloads page. ($499 new, free update, 210.91 MB)
Two Shortcuts for App Exposé
If you want to see all the windows for a particular app via App Exposé, there are two hidden shortcuts. For either, start by pressing Command-Tab to bring up the app switcher. Then, while still holding down the Command key, press either the 1 key or the up arrow. That puts you into App Expose mode, with all of an app's windows showing, and recent documents in a row across the bottom of the screen. Let up on the Command key, and then you can press Tab to cycle through all the running apps.
