* AudioSuite plug-in format takes the first channel of the side-chain track. While ARA supports multitrack reference. This might result in some differences between AudioSuite and VST3.

** ARA2 (Audio Random Access) isn't permanent, It gives Auto-Align Post access to the entire audio.

In Nuendo 12 you can use the 'Make Extension Permanent' option in order to commit Auto-Align Post's processing.
