Apple-owned Emagic has released Logic Audio Pro version 6.4.2, the latest update to its Logic Platinum software for computer-based music production.

Emagic says the new version "simplifies the licence management on the XSKy and fixes a few problems in the Mac OS X version".

According to Emagic's update information the fixes include improved OMF import and export, improved support for AU plug-in tempo synchronization, and improved sample rate switching for certain audio drivers. Crossfades now use "equal power" as defaultfade form, and unused controls on control surfaces no longer create unwanted MIDI events.

The 19.5M update requires Mac OS X 10.2 or higher and XSKey with Logic Platinum Mac authorization.
