Groove Agent SE5 with Cubase 12 - No Kits and Error

I just installed Cubase Pro 12 and also installed the Groove Agent SE5 VST and content.

When I open the Groove Agent VST I don’t see any kits in the library.

If I click the dropdown kit browser from the top of the VST I can see different kits there but when I click on any of them I’m getting this error:

groove agent error

Can anyone help? This is a new install.

Looking at the Steinberg Library Manager I can see the locations of the libraries.

And in the C:\ProgramData\Steinberg\Content\VST Sound directory are all the .vstsound files. Somehow Groove Agent SE isn’t seeing these.

Well after much searching today I believe I had resolved my own issue. Just out of trial and error I was hovering over ever little icon an option in Groove Agent. Eventually I found this icon (Rescan Disk) and presto! All my kits that I have downloaded from the Download Manager appeared and are playable.

Maybe this will help someone else. I had uninstalled/reinstalled Groove Agent SE and re-downloaded the content several times before finding this.


It did help someone (ME). Thank you. I bought a Win11 laptop and loaded Cubase 12 Pro on it. This exact thing happened with Groove Agent SE5 and Halion Sonic SE3. Glad I found your post. Your Rescan Disk solution worked. Thanks for taking the time to share.

Thank you so much for having this issue and being diligent enough to fix it yourself XD I was this close to giving up on Cubase entirely.
