The update gives users total session and automation compatibility with earlier versions of Pro Tools, access to the complete library of UAD powered plug-ins in AAX 64 format and adds support for Pro Tools 11's offline bounce feature.
New functionality has also been added, including AudioSuite processing for file-based workflows, which allows you to process files and selections with UAD plug-ins, commit the changes and free up DSP. Multi-mono support has also been added so you can use UAD plug-ins on surround and stereo tracks with full linking and unlinking capability.
Windows users haven't been forgotten either. Universal Audio claim that UAD v7.4.1 public beta has proven both stable and reliable in their internal tests. They are currently working on full qualification testing on Mac OS X and finishing Windows 7 AAX 64 support. Both Mac and Windows will be shipping in early 2014.
