Audio Interfaces — Other Manufacturers

Digidesign does not test or verify other manufacturers' audio peripherals with our system. During beta testing of Pro Tools HD 7 software, we received feedback that installing Pro Tools HD 7 software may prevent a non-Digidesign audio interface from working. We therefore suggest that customers contact the manufacturer of their device to check on potential compatibility issues before upgrading to Pro Tools HD 7 software.

New Session File Format (".ptf")

Pro Tools 7.0 uses a new session file format and extension (.ptf) to distinguish its sessions from sessions created with previous versions. Pro Tools 7 sessions need to be saved as an earlier format to be used with pre-7.0 Pro Tools systems. For more information, see the following:

Energy Saver Settings

Pro Tools Does Not Support Sleep Mode

In the Macintosh System Preferences, launch Energy Saver, click the Sleep tab, and disable all Sleep features. Set "Put the computer to sleep when it is inactive" to Never. Do not manually put your computer to sleep when running Pro Tools.

Processor Performance & Power Mac G5

For optimal Pro Tools performance, you must set Processor Performance (located in System Preferences > Energy Saver > Options) to "Highest". Updating your Mac OS may reset this to the default setting: "Automatic". After updating your Mac OS, check to make sure this is set to "Highest".

Apple's Mac OS help documentation provides the following info on Energy Saver Processor settings:

  • The PowerPC G5 processor in your Power Mac G5 can run at various speeds. The default setting for this feature is "Automatic", which allows the system to run the processor at full speed when required, and at a lower speed during periods of light processing activity. Certain real-time applications, such as audio creation or gaming, may perform optimally when using the highest processor performance setting. You can change the processor performance setting in the Energy Saver pane of System Preferences.
