This error typically occurs when the software (like EZdrummer or Superior Drummer) is looking for its expansion packs (EZXs) or MIDI data in a directory that is either empty or incorrectly structured. Immediate Solutions
Locate the Folder Manually: If you have moved your library to an external drive, you must point the software to the correct root folder. In EZdrummer 3 or Superior Drummer 3, navigate to Settings > Libraries/Paths and use the Locate button to select the specific folder where your "SL-" (Superior) or "EZX_" folders are stored.
Check for Missing Content: Often, users install the software but forget to download the actual sound library. Open the Toontrack Product Manager and ensure the Sound Library (often labeled "Part 1 – Basic Sound Library") is fully downloaded and installed, not just the core application.
Force "Locate Folder" Visibility: If the software doesn't show a "Locate" option, a common workaround is to temporarily rename your library folder (e.g., add a "1" to the end). When you open the software, it will fail to find it and prompt you to manually select the folder, at which point you can select the original folder again. Advanced Fixes (Registry/System)
If the internal settings fail to save the path, you may need to manually update the system's record of where the files are kept: Windows Registry Fix:
Press Win + R, type regedit, and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Toontrack\Superior\EZDrummer.
Check the MidiPath value. Ensure it matches your actual MIDI folder path (e.g., C:\Program Files (x86)\Common Files\Toontrack\EZDrummer\Midi).
Permissions Check: Ensure the folder you selected has full read/write permissions. If installing to an external drive, ensure it is formatted as NTFS (Windows) or APFS/HFS+ (Mac), as ExFAT can sometimes cause pathing errors. Default Library Locations
If you didn't choose a custom path during installation, check these default locations:
For EZX/SDX drum libraries:
The folder should contain a file named EZX.dat (for EZX expansions) or SDX.dat (for Superior Drummer expansions). Without this file, Toontrack software will not recognize the library.
For EZkeys MIDI libraries:
The folder should contain a file named MIDI.dat.
If you open a folder and see these files, that’s the correct folder. If not, you’ve selected the wrong location.
Older versions of EZdrummer (e.g., EZdrummer 2) cannot read newer EZX formats designed for EZdrummer 3. Similarly, EZkeys 1.x cannot read newer MIDI packs.
This error message typically occurs in Toontrack software, such as EZdrummer or Superior Drummer, when the plugin cannot find its sound or MIDI data because the directory path is incorrect or the files are missing. Immediate Solutions
Correct the Library Path: Open the software's settings (usually Settings > Libraries/Paths) and ensure it points to the folder containing your sounds. For example, on Windows, the default is often C:/Program Files(x86)/Common Files/Toontrack/EZDrummer.
Remove "MIDI" from the Path: A common mistake is pointing the software directly to the MIDI subfolder. Try selecting the parent EZDrummer or Toontrack folder instead.
Download Core Libraries: If you recently installed the software or a trial version, ensure you have also downloaded and installed the Core Library (often 15GB or more) through the Toontrack Product Manager. Troubleshooting Checklist
The error message "no EZXs or MIDI libraries were found in the selected folder" no ezxs or midi libraries were found in the selected folder
occurs when Toontrack software (like EZdrummer or Superior Drummer) cannot find the required sound and MIDI files at the path specified in its settings
. This typically happens after moving library folders to an external drive or if the folder structure was accidentally modified. Common Fixes
This error typically occurs in Toontrack software (like EZdrummer or Superior Drummer) when the application cannot find the sound or MIDI data files in the directory you pointed it to. ⚡ Direct Solutions
Install the Core Library: If you just installed the plugin (the "software"), you must also download and install the Core Library (roughly 15GB) via the Toontrack Product Manager.
Select the Parent Folder: When browsing, do not select the "MIDI" or "Sounds" folder specifically. Select the Toontrack or EZDrummer folder that contains them.
Reset the Registry (Windows): If the path is stuck, open the Command Prompt as Admin and run:reg delete HKLM\SOFTWARE\WOW6432Node\Toontrack\Superior\EZdrummer /v MidiPath /f. 📂 Default Library Locations
If you didn't choose a custom path during installation, your files should be here:
Windows: C:\Program Files (x86)\Common Files\Toontrack\EZDrummer
macOS: Macintosh HD > Library > Application Support > EZDrummer 🛠️ Troubleshooting Steps 1. Check Installation Status Open the Toontrack Product Manager and verify: The product is Authorized.
The Sound Library and MIDI updates are both marked as "Installed". 2. Manual Path Re-linking If you moved your libraries to an external drive: Open the standalone EZdrummer app. Go to Settings > Libraries/Paths.
Look for a red "X" or yellow triangle. Click Edit Path and select the folder on your external drive. 3. Rebuild Database Within the plugin: Go to Settings > Advanced. Click Restore MIDI Database.
💡 Key Tip: If you are using an external SSD, ensure it is plugged in before opening your DAW or the standalone app, otherwise the software will default back to the "not found" error.

Troubleshooting "No EZXs or MIDI Libraries Were Found in the Selected Folder"
If you are a user of Toontrack’s EZdrummer or Superior Drummer, encountering the error message "No EZXs or MIDI libraries were found in the selected folder" can be incredibly frustrating. You’ve likely just installed a new expansion or moved your sound libraries to an external drive, only to find your software acting like they don’t exist. What does a valid EZX or MIDI library folder look like
The good news is that your files aren’t usually gone; the software simply lost the "map" to where they are stored. Here is a step-by-step guide to fixing this common pathing issue. 1. Verify the Installation Path
Before tweaking settings, you need to know where your sounds actually live. By default, Toontrack installs libraries to:
Windows: C:\Program Files (x86)\Common Files\Toontrack\EZDrummer macOS: /Library/Application Support/Toontrack/EZDrummer
If you used a custom location (like an external SSD), navigate to that folder in your File Explorer or Finder. You should see folders labeled "EZX_..." or "Midi". If these folders are missing from the directory you’ve selected, the error message is technically correct. 2. Update the Path in Toontrack Product Manager
The most common cause is a discrepancy between where the Toontrack Product Manager thinks the files are and where the DAW plugin is looking. Open the Toontrack Product Manager. Find your specific EZX or SDX expansion.
If it says "Path Not Found," click Show Details and use the Locate button to point it to the correct folder. Restart your DAW and reload the plugin. 3. Set the Libraries Path within the Plugin
If the Product Manager looks fine but the error persists inside EZdrummer or Superior Drummer: Open the plugin in your DAW. Go to the Settings or Settings > Libraries tab. Look for a button labeled Additional Libraries or Set Path. Browse to the parent folder that contains your EZX folders.
Note: Do not select the specific "EZX_PopRock" folder; select the "EZDrummer" folder that contains all the individual expansions. 4. Check Permissions (macOS Especially)
If you are on a Mac and your libraries are on an external drive, macOS might be blocking the plugin from "reading" the drive.
Go to System Settings > Privacy & Security > Full Disk Access.
Make sure your DAW (Logic, Ableton, Cubase, etc.) is toggled ON. This allows the plugin hosted within the DAW to see your external folders. 5. Re-Authorize Your Products
Sometimes, the library is found, but the license communication fails, triggering a generic "not found" error.
In the Product Manager, check if the library needs to be Authorized.
If it’s already authorized, try clicking Refresh or logging out and back into the Product Manager to sync your serial numbers. Summary Checklist
Are the EZX folders actually in the folder? (Check for EZX_ prefixes). Is the drive connected? (If using an external SSD).
Did you select the Parent folder? (Select .../Toontrack/EZDrummer, not the specific expansion folder).
By following these steps, you should be back to making music in minutes. Most often, a quick re-link in the Settings menu of the plugin is all it takes to resolve the "No EZXs found" headache.
