Opening the right zone > Loops & Samples… suddenly it is empty. This happened shortly after Pro 12 came out too. Then, I reinstalled everything from the Download Assistant. This time, it is still empty!?!
Help!!!
is there a folder in Steinberg on my PC where I can manually correct this?
Many thanks
The solution is similar to these instructions: FLUX Wavetable Synth missing in HALion Sonic SE 3
I’ve edited them for Cubase users:
Windows
- Close all programs.
- Open the “Run” command prompt by pressing the Windows logo key + R simultaneously.
- In the command line of the ‘Run’ window, enter one of the following path shortcuts::
user specific installation (standard): %appdata%
installation “for all users”: %programdata%
Simply use %appdata% if you are in doubt.
- A new Windows Explorer Window opens.
- Locate the folder ‘Steinberg’ and open the folder ‘Cubase 12_64’.
If you can’t find the folder or files, please try again using the other path shortcut. - Delete these files (to keep a backup, simply copy them to the Desktop before):
ContentManager.xml
mediabay3.db
scannedFolders3.bin
Next time you start Cubase, the deleted files will be rebuilt.
macOS/Mac OS X
- Close all programs.
- In Finder, open the Go to Folder dialog by pressing cmd + Shift + G or via the Go menu.
- Enter this path shortcut: ~/Library/Preferences
(Copy and paste recommended.) - A new Finder window opens (Preferences).
- Open the contained folder ‘Cubase 12_64’.
- Delete the following files (to keep a backup, simply copy them to the Desktop before):
ContentManager.xml
mediabay3.db
scannedFolders3.bin

Hello everyone,
I have the same issue here.
When i want to see my loops and sample from rigth zone :
In cubase 11 all loop and sample libraries are displayed (see picture)
But in cubase 12 there is only one.
It’s not a problem of a particular instrument, it’s the library itself that is not correctly scanned I think.
If anyone knows the solution it would be a great help.
Thank you very much.

ok i find the solution in a post about cubase 10
for windows users : go to: C:\Users\XXX\AppData\Roaming\Steinberg\cubaseXXX - with your windows username and the cubase version instead of XXX (obviously!) there is a file in there called something like mediabay3.db ? (I THINK!) rename it to mediabay3.bak restart cubase…
if you use the search tool in explorer who will find several “mediabay3db” rename only those necessary
Thank’s to Romantique_Tp, you : you were on the right road ;D
it’s great to work together! you are a great community

hello
i has this the other day , i fixed it by opening media bay , opening the VST sounds folder in the left pain , then right click on a loop set , select rescan disk or quick rescan disk , and then just go through all the loop sets and do the same thing , may also need a restart , after that all the loop sets were visible again
cheers !!
