OpenTL open track list file
File type: Audio and sound file
A .tl file is an OpenTL (Open Track List) exchange file for audio projects. It is associated with Tascam hard-disk recorders and Apple Logic Pro.
The file describes audio media and how that media is used in a project; it is not a general-purpose audio file.

OpenTL is an audio track-list format for exchanging project information with Tascam hard-disk recorders, including the MX2424. A .tl file can describe the audio media in a project and the way that media is arranged and used on its tracks.
The format is intended for project interchange rather than ordinary audio playback. It is used together with the associated audio media, allowing a compatible application to reconstruct the track layout and project use of that media.
Apple Logic Pro supports OpenTL on Apple macOS and Mac OS X.
Open or import the .tl file in Apple Logic Pro on macOS or Mac OS X. Logic Pro may also require access to the audio media referenced by the track list.
Because OpenTL is an exchange format, opening the file does not necessarily provide playable audio if its associated media is missing.
OpenTL files are generally exchanged between Tascam devices and programs that support the format. You can import the file into a compatible application such as Apple Logic Pro, then save the imported project in Logic Pro's native format or export its audio in a suitable audio format.
