Surround : Pro Tools Setup for Surround : Configuring Pro Tools for Multichannel Sessions : Importing Multichannel I/O Setups

Importing Multichannel I/O Setups
The I/O Setup dialog can import and export settings files. This is useful when you want to remix a stereo session in surround. You can also use this feature to prepare a session for transfer to a different Pro Tools system, or to save and exchange I/O Settings.
To import a multichannel I/O Setup settings file:
1 Choose Setup > I/O.
2 Click the Output tab.
3 Click Import Settings.
4 Select the settings file (.pio) to import and click Open.
5 If the current session has path definitions that do not match those in the imported settings file, Pro Tools asks whether you want to delete the existing paths or retain them and add the imported settings to your session.
*   
Click No to add new paths to your current I/O Setup configuration.
*   
Click Yes to replace your current I/O Setup configuration with the imported settings.
6 Click the Bus tab.
7 If the Bus page does not show the correct output bus mappings for the imported I/O Settings file, click the Default button (for All Busses or for Output Busses).
8 Click OK to close the I/O Setup.
