Hi all,i’ve just opened up an old project to find that all my audio tracks have gone missing,there is nothing in the edit window,these are all sounds recorded from external sources.
A couple of thoughts…
Have you somehow hid the tracks? Check the track visibility menu.
Have you checked the project audio pool? The recordings should be there if you properly imported them. If they are there at least you could re-create the project.
Regards
