Pro Tools LE, first introduced and distributed in 1999 with the Digi 001 interface,<ref name=":4">{{Cite web|url=http://www.soundonsound.com/sos/dec99/articles/digi001.htm|title=Digidesign Digi 001|date=December 1999|website=[[Sound on Sound]]|url-status=dead|archive-url=https://web.archive.org/web/20150609073618/http://www.soundonsound.com/sos/dec99/articles/digi001.htm|archive-date=2015-06-09|access-date=2018-02-06}}</ref> was a specific Pro Tools version in which the signal processing entirely relied on the host CPU. The software required a Digidesign interface to run, which acted as a copy-protection mechanism for the software. Mbox was the entry-level range of the available interface; Digi 001 and Digi 002/003, which also provided a control surface, were the upper range. The Eleven Rack also ran on Pro Tools LE, included in-box DSP processing via an FPGA chip, offloading guitar amp/speaker emulation, and guitar effects plug-in processing to the interface, allowing them to run without taxing the host system.

Pro Tools LE shared the same interface of Pro Tools HD but had a smaller track count (24 tracks with Pro Tools 5, extended to 32 tracks with Pro Tools 6<ref name=":10" /> and 48 tracks with Pro Tools 8)<ref name=":17">{{Cite web|url=https://www.soundonsound.com/reviews/digidesign-pro-tools-8-part-2|title=Digidesign Pro Tools 8: Part 2|last=Mark|first=Wherry|date=February 2009|website=[[Sound on Sound]]|access-date=2019-12-18}}</ref> and supported a maximum sample rate of 96&nbsp;kHz<ref name=":22" /> (depending on the interface used). Some advanced software features, such as Automatic Delay Compensation, surround mixing, multi-track Beat Detective, OMF/AAF support, and [[Timecode|SMPTE Timecode]], were omitted. Some of them, as well as support for 48 tracks/96 voices (extended to 64 tracks/128 voices with Pro Tools 8) and additional plug-ins, were made available through an expansion package called "Music Production Toolkit".<ref>{{Cite web|url=https://www.soundonsound.com/reviews/digidesign-hybrid-music-production-toolkit|title=Digidesign Hybrid & Music Production Toolkit|last=Inglis|first=Sam|date=June 2006|website=[[Sound on Sound]]|access-date=2019-12-18}}</ref> The "Complete Production Toolkit", introduced with Pro Tools 8, added support for surround mixing and 128 tracks (while the system was still limited to 128 voices).<ref name=":17" />

With the acquisition of [[M-Audio]] in 2004–2005, Digidesign released a specific variant of Pro Tools, called {{Nowrap|M-Powered}}, which was equivalent to Pro Tools LE and could be run with M-Audio interfaces.<ref name=":18">{{Cite web|url=https://www.soundonsound.com/reviews/pro-tools-m-powered|title=Pro Tools M-Powered|last=Inglis|first=Sam|date=June 2005|website=[[Sound on Sound]]|language=en-gb|access-date=2018-02-05}}</ref>

The Pro Tools LE/{{Nowrap|M-Powered}} line was discontinued with the release of Pro Tools 9.
