Mixing : Plug-In and Hardware Inserts : Plug-In Mapping : Setting a Custom Plug-In Map as the Default Map

Setting a Custom Plug-In Map as the Default Map
You can set a custom plug-in map as the default map for a plug-in, instead of the Factory Default map.
When you set a custom plug-in map as the default, it applies across the entire session. All instances of that plug-in that were set to the Factory Default map, or to another custom default map, change to the new default.
If you change parameter mapping in the custom plug-in map that has been set as the default, the changes will propagate to all instances of the plug-in using that default.
*
When you export a plug-in map, the default map setting for that plug-in is also exported. When that map is imported, the default setting is also updated, and all instances of the plug-in change to the new default.
How Default Plug-In Map Settings are Stored
Default map settings are stored as global (system-wide) Pro Tools preferences, so they are applied to all sessions that you subsequently open or create on that system.
*
If you plan to work with the same plug-in mapping on multiple sessions, back up your settings by exporting all plug-in maps on a regular basis and saving the .pim file with your sessions.
To set a custom plug-in map as the default plug-in map:
1 Open the plug-in whose default plug-in map you want to change.
2 Choose the map you want to use as the new default from the Map Presets pop-up menu.
3 From the Map Options pop-up menu, choose Set As Default.
