Sessions & Tracks : Sessions : Opening a Session with Plug‑Ins Deactivated

Opening a Session with Plug‑Ins Deactivated
Pro Tools lets you open sessions with all of the session’s plug-ins set to inactive. Since sessions with a lot of plug-ins can take a long time to load, this lets you quickly open any session for immediate visual inspection and audio playback (without plug-ins). If it is the session that you want to work with, you can easily reopen the session with plug-ins activated.
To open a Pro Tools session with all plug-ins set to inactive:
1 In Pro Tools, choose File > Open Session.
2 In the Open Session dialog, locate and select the session you want.
3 Shift-click Open.
To re-open the same session with all plug-ins set to active, do one of the following:
*
Choose File > Revert To Saved.
– or – 
*
Choose File > Open Recent and select the most recent session in the submenu.
*
Press Control+Shift+O (Windows) or Command+Shift+O (Mac) to open the most recent session.
*
Instead of reverting to the saved version of the session to open the session with all plug-ins active, you can simply make an individual plug-in active by Control-Start-clicking (Windows) or Command-Control-clicking (Mac) it. To make an entire row of plug-ins active, Control-Alt-Start-click (Windows) or Command-Option-Control-click (Mac) any plug-in in the row of inserts.
