    Assets Or License Not Found

    If you are having trouble with Bliss, Corona, Discovery, Discovery Pro or OB-Xd and seeing a file missing or getting a license invalid error, one possible solution to this issue could be to disable iCloud Documents. This is because it might be interfering with the software's ability to access the necessary files.

    Additionally, we recommend checking if there are any files existing at the user's "Documents > discoDSP > Corona / Bliss / Discovery / Discovery Pro / OB-Xd" folders. If the folder is empty or doesn't exist, it could be the reason why the software is not able to locate the assets or the license file.

    It's also worth checking that Logic Pro or the DAW app has access to the "Documents" folder under Security settings on your Mac. This can be done by going to System Preferences > Security & Privacy > Privacy, then select the "Files and Folders" tab, and look for the "Logic Pro" or DAW application in the list of apps. Make sure it has permission to access the "Documents" folder.

    Plugins Not Appearing in Logic Pro

    First Solution

    Try rebooting your computer. This can often resolve any software conflicts or issues that may be preventing your plugins from appearing in Logic Pro.

    Second Solution

    Open Terminal and use the command

    sudo killall -9 AudioComponentRegistrar

    This command will force quit the AudioComponentRegistrar process, which is responsible for managing audio units in macOS. Killing the AudioComponentRegistrar process is a temporary solution used to avoid the need for a reboot. It should not have any significant impact on the system. However, it's always recommended to reboot and avoid force quitting system processes.

    Third Solution

    1. In Finder, go to Go > Go to Folder in the menu bar at the top.
    2. Copy-paste the following path and click Go: ~/Library/Caches
    3. Delete any folder named AudioUnitCache.
    4. Delete any file named
    5. Reboot the system.

    Fourth Solution

    1. In Finder, go to Go > Go to Folder in the menu bar at the top.
    2. Copy-paste the following path and click Go: ~/Library/
    3. After opening the library, navigate to the locations listed below and move the specified files to the Trash:
      • ~/Library/Caches/ (Files: Cache.db, Cache.db-shm, Cache.db-wal)
      • ~/Library/Preferences/ (File:
      • ~/Library/Preferences/ (File:
    4. Once the files are moved, empty the Trash.
    5. Finally, restart your Mac for the changes to take effect.

    Note: Ensure you're logged in as an Admin account to perform these steps, or you might not have the necessary permissions.

    GUI Image or Bliss File Import Issues in Linux

    In some cases, the document folder path may not be set properly on your Linux distribution, which could cause the GUI not to load or LUA scripts to fail to import files in Bliss. Please check if the document folder path is set correctly on your system.


    You need to display the $(xdg-user-dir DOCUMENTS) folder path in Linux but are unsure how to do it.


    To display the $(xdg-user-dir DOCUMENTS) folder path in Linux, you can use the following terminal command:


    This command will print the full path to your Documents folder. If the folder path is not set correctly, you can try setting it manually by creating a .config/user-dirs.dirs file in your home directory and adding the following line:


    Replace "Documents" with the desired name of your Documents folder. After saving the changes, log out and log back in to apply the changes.


    By using the terminal command and creating a .config/user-dirs.dirs file, you can easily display and set the $(xdg-user-dir DOCUMENTS) folder path in Linux.

    Bliss Sampling Truncated Soundbanks

    If you've tried to resample soundbanks with Bliss and found that some notes appear truncated or incorrectly rendered, you're not alone. Many users have reported this issue while trying to resample plugins like Kontakt, UVI Workstation or Cherry Audio. In this article, we'll explore the cause of this problem and provide a solution to resolve it.

    Cause of the Problem

    The cause of the truncated notes issue lies in some kind of offline sampling protection implemented by Kontakt and UVI Workstation. These plugins interfere with the resampling process in Bliss, resulting in truncated notes.


    The solution to this issue is to use a bridge such as DDMF Metasynth to load Kontakt. A bridge acts as a middleman between Bliss and the soundbank, bypassing the offline sampling protection and allowing for a successful resampling process.

    How to use DDMF Metasynth

    1. Visit the DDMF website and download the free demo of DDMF Metasynth.
    2. Install DDMF Metasynth on your computer.
    3. Load Kontakt through DDMF Metasynth instead of loading it directly into Bliss.
    4. Try resampling the soundbank again. The truncated notes should no longer be a problem.


    By using DDMF Metasynth as a bridge, you can successfully resample soundbanks with Bliss, even if they were previously truncated. Give it a try and let us know if it works for you. If you're still facing issues, feel free to reach out to us for further assistance.

    Plugin Can't Load SF2

    If you are having trouble using SoundFont2 files in the Wave oscillator of your Discovery Pro, Corona or Bliss plug-ins, there may be an issue with the format of the SF2 file. Some SF2 files may contain multiple programs within them, which can cause the software to not recognize or use the file correctly.

    To resolve this issue, you can use a SF2 editor to extract the desired program from the SF2 file and save it as a single program. This will allow the Discovery Pro software to recognize and use the program correctly.

    One popular SF2 editor we recommend is Polyphone. It is a free and open-source software that allows you to edit, create, and convert SoundFont files. You can download it from their website at

    Here are the steps you can take to use Polyphone and fix the issue with your SF2 files:

    1. Download and install Polyphone from
    2. Open the SF2 file that you wish to use in Polyphone.
    3. In the "Presets" tab, select the program you wish to use and right-click it.
    4. Select "Export Soundfonts" from the context menu.
    5. Save the new SF2 file that contains only the desired program.
    6. Place the SF2 into Documents > discoDSP > Discovery Pro > Waves or Documents > discoDSP > Corona > Waves > folder.
    7. In Discovery Pro, go to the Wave oscillator and select the newly created SF2 file. In Corona, use the oscillator drop down menu.
    8. The program should now be recognized and usable.

    Additionally, on step 5, you can also export as SFZ and import the WAV files instead of dropping them into the GUI. They will be copied to Waves > User.dwb folder.
