Pro Tools Session File Repair, Conversion, Relinking

Using a modern Pro Tools setup (on either Mac or Windows) you might run into problems opening sessions created in the 90's to early 2000's (PT1 to PT 5) on Mac System 7.x, 8.x, and OS 9.x, OSX 10.0.x - 10.4.x which may report missing audio files. Even after searching and locating the files on the hard drive, Pro Tools will often still be unable to bring them into the session. This because Sound Designer 2 (aka SD2 or SDII) file format was dropped in Pro Tools 10. However, there could be worse problems. Project files are stored on a disk that is not the HFS (Hierarchical File System) native Mac format, such as a Windows disk format like FAT32, ExFat, or NTFS without first being zipped (.zip) or stuffed (using Aladdin Systems Stuffit .sit format) can have the SD2 file resource fork stripped out, which contains the audio bit rate and sample frequency. PT 10 was the last version to work with SD2 files but the on-board re-linking and converting to .wav files does not always work right or can be very cumbersome to relink manually. Deep Signal Studios can resolve these issues and repair Pro Tools files in situations where SD2 files can not be played in the session file. We can also convert Pro Tools sessions made in 10 or 11 to PT7, PT8, or PT9 session. In addition to repairing and restoring Pro Tools files, we can convert your Pro Tools projects for use in other 2024 DAW formats including Logic, Digital Performer, Cubase, Ableton, Garage Band, or any other DAW or sequencer file format you wish by exporting each track as a .wav file. We can retrieve sessions from Jaz, Zip, DDS tapes, or DVD-RAM.

Please read these details on the right way to transfer old Mac files to a modern computer while keeping the resource fork intact for the purpose of emailing a download link to us so we can convert them.

If your Pro Tools session files have one of these icons below that is visible in current MacOS (or still using a machine from that period) they, along with your SD2 files, will probably be OK as long as you zip them. Pro Tools Windows session files will not have any of the above problems.
