Logic Pro 9.1, Main Stage 2.1 Add 64-bit Support

| Product News

Apple rolled out Logic Pro 9.1 and MainStage 2.1 late on Tuesday with the ability to run in 64-bit mode instead of just 32-bit mode. Logic Pro is Apple's professional audio editing application, and Main Stage is the company's live performance audio editing application.

Enabling 64-bit support in both applications lets Logic Pro and Main Stage access more memory than the 32-bit versions can handle, allowing for potentially better overall application performance.

Logic Pro 9.1 also added support for 64-bit Audio Unit plug-ins, file names with more than 32 characters, and now correctly maps contiguous zones in the EXS editor. The update requires Mac OS X 10.5.7 or higher for 32-bit mode and Mac OS X 10.6.2 or higher for 64-bit mode.

Main Stage 2.1 also added support for 64-bit Audio Unit plug-ins, improved compatibility with Main Stage 1.x files, improved Loopback recording, and fixed an issue where Multiple Playback plug-ins in the same group didn't sync reliably. The update requires Mac OS X 10.5.7 or higher for 32-bit mode and Mac OS X 10.6.2 or higher for 64-bit mode.

The updates are available via the Software Update application, or as downloadable installers at the Apple Support Web site.
