==== Hardware-independent native systems: Pro Tools 9 ====
Pro Tools 9, released in November 2010, dropped the requirement of proprietary hardware to run the software. Any audio device could be used through [[Core Audio]] on macOS or the [[Audio Stream Input/Output|ASIO]] driver on a Windows. Core Audio allowed device aggregation, enabling using of more than one interface simultaneously. Some Pro Tools HD software features, such as automatic plug-in delay compensation, OMF/AAF file import, Timecode ruler, and multi-track Beat Detective, were included in the standard version of Pro Tools 9.<ref name=":23">{{Cite web|last=Inglis|first=Sam|date=January 2011|title=Avid Pro Tools 9|url=https://www.soundonsound.com/reviews/avid-pro-tools-9|access-date=2018-02-04|website=[[Sound on Sound]]|language=en-gb}}</ref>

When operating on a machine containing one or more HD Core, Accel, or Native cards, the software ran as Pro Tools HD with the complete HD feature set. In all other cases, it ran as Pro Tools 9 standard, with a smaller track count and some advanced features turned off.
