As well as the headline features, Avid also made some less obvious changes in Pro Tools 10, some of which are very useful. Among these are improvements to the Save Session Copy and Import Session Data functions.

To save a copy of the current session in a ‘snapshot’ state that won’t be updated as you continue to work, as it would if you used ‘Save Session As’.
