How to Fix Missing Expansions in Omnisphere 2

Missing expansions in Omnisphere 2 can be a creativity roadblock—especially when you already have the expansions downloaded, but the plugin won’t recognize them. Fortunately, the solution typically comes down to pointing Omnisphere to the right directory and ensuring your folder structure is correct. Follow these steps to get all your patches and sounds back where they belong.
Common Error Messages
Error Message | Meaning | Likely Cause |
---|---|---|
Cannot Locate STEAM Folder | Omnisphere can’t find its main library path. | STEAM folder moved or placed in an unexpected directory. |
Missing SoundSource | Omnisphere can’t see the expansions’ data files. | Incorrect folder placement, or partial extraction. |
Patch Loading Failed | Omnisphere can’t load a specific patch. | Misplaced expansion folder or corrupted file structure. |
Most of these messages revolve around Omnisphere not finding the STEAM folder where all the expansions live.
1. Confirm Your STEAM Folder Path
By default, Omnisphere expects a particular directory setup for its sounds and expansions:
- Windows (typical):
C:\Program Files\Spectrasonics\STEAM
- macOS (typical):
/Users/Username/Library/Application Support/Spectrasonics/STEAM
If you’ve placed your expansions (like Keyscape Creative or Moog Tribute Library) inside subfolders, ensure they’re indeed in the STEAM
folder that Omnisphere is referencing. Sometimes expansions get placed in a second nested “STEAM” folder, which confuses the plugin.
2. Relocate the STEAM Folder in Omnisphere
If you’ve moved your STEAM folder to a new drive or a different location to free up space, Omnisphere might still be looking in the old spot. To fix this:
- Open Omnisphere 2 (standalone or in your DAW).
- Look for an option like “Locate STEAM Folder” in the plugin’s Settings or Utility menu.
- Navigate to the folder where your STEAM directory currently lives.
- Confirm or press OK, and let Omnisphere rescan.
Typically, Omnisphere will search that STEAM folder for any missing expansions and re-link them.
3. Verify Expansion Folder Structure
Even if the folder is correctly placed, expansions can go undetected if they’re in the wrong subfolder. For instance, your expansions might belong here:
STEAM/Omnisphere/Patches
STEAM/Omnisphere/Soundsources
STEAM/Omnisphere/Settings Library
Double-check:
- You haven’t extracted expansions into nested directories (e.g.,
STEAM/STEAM/Omnisphere/...
). - The expansions’ subfolders match Omnisphere’s expected naming conventions.
4. Force a Library Rescan
When in doubt, a manual rescan often fixes the problem. Here’s how:
- Open Omnisphere in your DAW or as a standalone.
- Go to Settings > Sound Management (or a similar tab).
- Click “Re-scan” or “Refresh” library.
- Wait for the progress bar to complete, then test a few patches to see if they show up.
If your expansions are still hidden, close and relaunch your DAW—sometimes Omnisphere needs a restart to finalize updates.
5. Check Permissions
If you run into continued errors, it might be a file-permission issue:
- Ensure your user account has read and write access to the entire STEAM folder.
- On Windows, you can right-click the folder > Properties > Security.
- On macOS, select the folder > Get Info > Sharing & Permissions.
Without proper permissions, Omnisphere might fail to load certain expansions or patch data.
Still Having Issues?
If you’ve confirmed the folder path, verified permissions, and performed a rescan but certain expansions remain invisible, it could mean the expansions were partially copied or structured incorrectly. Try reorganizing or re-extracting them into the correct subfolder paths, and then rescan one more time.

Conclusion
Missing expansions in Omnisphere 2 often boil down to folder location or subfolder organization. A quick relocation, a manual rescan, and verifying permissions typically solve most issues in minutes.
