So when you say you have the recovery files, does this include the Audio files & the Cubase Project file?
If you have the project file…
Create a folder, drop the project file into that folder, also create a folder called ‘audio’ in the same folder with the project. Dump ALL the recovered audio files into the audio folder. Open the Cubase project, if it cannot find the files
make sure it is looking at the audio folder. If is still cannot find all the files, let it search your recovery drive, or the original drive. If it still cannot find some files you may never find them. BUT they also may be files you do not need (i.e. files that were deleted on purpose). So close the missing file window and look at the Cubase project to see if
anything looks missing.
The point is, even if (from the file names) you cannot tell what goes where, the Cubase project does.
If you do find all the files, archive off a safety NOW. use “prepare archive” this copies all files from ANY drives into the projects audio folder, then Save as new project, check the boxes for remove unused files, freeze edits, then save.
Good luck!
