Miscellaneous

Increasing the Number of Input/Output Parameters and Strings

By default, Plug'n Script creates 48 input parameters, 32 output parameters, and 16 input and output strings. If these defaults are insufficient for your project, you can increase them using a simple workaround.

Create a config.ini text file in your PnS documents root folder (~/Documents/Blue Cat Audio/Blue Cat's Plug'n Script) with the following content:

  1. maxInputParamsCount=64
  2. maxOutputParamsCount=64
  3. maxPrivateOutputParamsCount=64
  4. maxInputStringsCount=32
  5. maxOutputStringsCount=32

All values are optional. After saving your changes, reload Plug'n Script.

Clearing the AU Plugins Cache

In rare cases, if you experience issues with AU plugins, you may need to perform a full rescan and clear the AU cache. To do this:

  • Quit Logic
  • Remove the ~/Library/Caches/AudioUnitCache folder
  • Remove the ~/Library/Caches/com.apple.logic10 or 11 folder
  • Remove the ~/Library/Preferences/com.apple.audio.InfoHelper.plist file
  • Restart your Mac
  • Launch Logic

Locating Global Preferences

For exported PnS plugins on Mac, global preferences are stored at the following location:
~/Library/Preferences/[MANUFACTURER]/[Plug-in name and TYPE]

On Windows, the preferences can be found under:
~/AppData/Roaming/[MANUFACTURER]/[Plug-in name and TYPE]

Using Entitlements

When exporting an application on Mac, Plug'n Script generates a ".entitlements" file. This file is used during signing and notarization. For example, you can sign your app using:

codesign /path/to/your/app -s 'Developer ID Application: Your Apple Certificate (XXXXXXXX)' --timestamp -deep --options runtime --force --entitlements appname.entitlements
