Missing mono audio tracks

Hello, after an upgrade from cubase 13 to cubase 15 I am experiencing missing mono audio files in every one of the nine songs.

I have got sologuitar files recorded in mono left and mono right on every song, and now the pool cant find them anymore.

I recently installed biab 2026

I am working on windows 11 with cubase 13 and 15

RME fireface 802 is my ADDA

I have made backups of the complete audio tracks several times, so they must be on my harddisks somewhere, but still the audio pool cant find my missing tracks, even when i scan all the harddisks for them.

i have made edits in the mono audio tracks like fade out etc.

What could have happened?

Can somebody help please?

have you checked the “Audio” folder that’s a subdirectory of your project folder?

Yes, thats where all my audio files should be.

I cannot find the missing ones, even in the backup files

In one song i have some mono audio files left there and they are big files (17minutes or longer) because i did the recording in a cycle loop. (To be able to pick out the best recording)

in the edits folder I have the edits to the files I am missing.

So I am missing mono audio files made from looping a song 3 or 4 times.
