Bad performance (macOS & Windows)

If you have any issues related to performance, high CPU usage, and audio dropouts/crackling noises, please take a look at the following info:

Be sure that your audio settings are correctly configured. If you're not sure about the optimal settings, try to replicate these:

  • Audio Device Type (Windows Only): ASIO

  • Audio Input Device: (This will vary depending on your audio interface)

  • Audio Output Device: (Select the same device as above)

  • Audio Output Channels: L and R / 1 and 2

  • Audio Input Channels: Input 1 or 2 (Disable all the inputs you're not using)

  • Sample Rate: 44100 Hz

  • Buffer Size: 128 or 256 Samples

After that, take a look at the optimization guide depending on which operating system you're using: Windows | macOS


Muted Standalone (macOS)

First of all, make sure you have just one input enabled at the audio settings, then check your mic permissions to allow the app to use the mic:

  • Select System Preferences from the Apple menu. 

  • Click the icon labeled Security & Privacy.

  • Click the Privacy tab at the top. 

  • In the lefthand column, click on Microphone to manage app permissions. 

  • Tick the boxes next to apps for which you’d like to grant access to the mic.

If you have the mic permissions granted no input signal, download and execute this file, then close it and launch the standalone version. Click on "allow" when it asks for mic permissions.

If you can’t run the file, open the Terminal app, and write “tccutil reset Microphone”. Then, hit enter and write your password to confirm.



Can’t run the PKG installer (macOS)

Try to run the PKG installer by right-clicking on it and select “Open”. If that doesn’t work, try this:

Some applications are not signed by Apple and will not be able to be installed. If you trust the application and know you want to install it, follow these steps to allow third-party apps to install.

  • Open "System Preferences" by clicking on the Apple icon and choosing that option.

  • Select "Security & Privacy" from the "System Preferences" window.

  • Select the "General" tab, and select the lock in the lower-left corner to allow changes.

  • Enter your computer username and password, then select "Unlock."

  • In the "Allow apps downloaded from:" section, select the radio button to the left of "Anywhere" or "App Store and identified developers".


Running plugins with older OS (macOS)

Please, go to your DAW app under the Applications folder, right-click on it and select “get info”.

Then, uncheck the box that says “32-bit” and restart your system.


AudioUnit updates VS older versions (macOS)

You can download the earlier version, and make sure you have your old sessions working.

Then you can make a copy of the AU file as a backup, then you can update the plugin to the latest version. After that, you can change the name of the updated file to make the difference. 

Finally, you can move the backup to the component folder.

Unfortunately, due to AU format limitations, if the plugin got new features in recent updates, such as MIDI implementation, it will be recognized as a different plugin. This is a problem of AU and the only solution is to save presets and reload them in the new version. Older versions of our products are always available on our site and you are free to make personal backups of those installers too.  

You can check this info in the Changelog files here:


Standalone crashes when selecting ASIO or doesn't launch


Most of the times, this is caused by driver issues or by a difference in the sample rate of your system and the sample rate of the application
  • Go to C:\Users\Your profile\AppData\Roaming\
  • Open the folder of the application that crashes (ex: Fortin Cali Suite)
  • Locate the .settings file (ex: Fortin Cali Suite.settings) and open it
  • At the bottom of the file, you will find a section describing the settings with which the application will initiate. You can modify the line "<DEVICESETUP deviceType="..." " to "ASIO", this way, the application will launch with the correct device already selected.
  • You can also copy the entire settings from another application that already works for you:


  • If for some reason the .settings file doesn't exist, you can copy the file from another application and change the name of it  (ex: Darkglass Ultra.settings = Fortin Cali Suite.settings).


Standalone crashes when changing the buffer size

Also caused by driver issues. 

  • Open the standalone application, set the Audio Device Type as "ASIO" and select your interface at Audio Device
  •  Don't change the buffer size and close the application
  • Open the control application of your audio driver (usually found on your Task Bar or in the Start menu) and change the buffer size from there
  • Open the standalone. The buffer size selected in the control application should override the buffer size of the standalone.  


Can’t save/load presets (macOS & Windows)

Try the following:

1 - Make sure that all the presets are installed in your system and that you don’t have any duplicated presets. These are the locations. Reinstall the application if you can’t find any presets:

  • macOS: MacintoshHD / Library / Audio / Presets / Neural DSP /

  • Windows: C:/ ProgramData / Neural DSP

2 - If everything looks fine, try deleting the Default preset (make a backup of it) and launch the application/open the Plugin.

3 - If that doesn’t work, try deleting all the presets (again, make a backup of them), launch the application and try to save a new custom preset. If you’re able to create a new preset file, copy all the factory presets back on the original preset folder.

4 - (Windows only) Verify the folder attributes:

  • Go to C:\ ProgramData \ Neural DSP \

  • Right-click over the Plugin preset folder (Ex: Fortin Nameless Suite) and disable "Read-only" in the attributes section. Then click Apply and OK.

  • You may need to change your account privileges. Open the "Security" tab > Select your user account > Press "Edit" > check every item on the "allow" column > Apply and OK.

After that, check if the issue persists.


I can't hear audio from other sources when using the application (Windows)

  • Go to Control Panel > Sound and check that your audio interface is set as the default device in the “Playback” and “Recording” tabs. Be sure that you have only one audio device running at a time in each tab. Double click on the device at the “Playback” tab (or select it and click on “Properties”) and verify if you're using the same sample rate as the application/plugin. Also, try switching between 16 and 24 bit.
  • Disable Exclusive mode (Control Panel > Sound > Double click on the device > Advanced > Uncheck “Allow applications to take exclusive control of this device”).
  • Right-clicking on the Volume icon in Windows > Open sound settings > App volume and device preferences > Make sure that every output is set to your Audio interface.
