Protools has a an internal feature -called- playlists, but it is not what media player’s software call playlists.
It is just to change the version of each track recording takes, considering each track inside the multitrack area as a playlist for whatever it has inside, different events, takes, items, regions... whatever...(I don’t know the exact name of these audio or midi regions in protools).
I’m not sure... but I don’t think that pt can save playlists in the sense of media player’s meaning of the word
