Problem
Even though the plug-ins are correctly installed, Dorico 6 does not find HALion Sonic 7 and Groove Agent SE 5.
The following error message appears:
An essential component used by Dorico for playback has not been found.
Please run the Steinberg Download Assistant and install the following:
HALion Sonic 7 - Instrument
Groove Agent SE 5 - Instrument
Background
In some cases, Dorico's plug-in scanner incorrectly adds both plug-ins to the blacklist, causing them to be ignored.
Solution
A fix will be provided with one of the next maintenance updates.
To resolve this issue immediately, please follow these steps:
- Open Dorico 6.
- Open Dorico's preferences:
- macOS: Select "Preferences..." from the "Dorico" menu.
- Windows: Select "Preferences..." from the "Edit" menu.
- Select the "VST Plug-ins" category.
- Scroll to the bottom and click "Reset Audio Engine Data".
- Quit Dorico.
The next time you start Dorico, both HALion Sonic 7 and Groove Agent 5 will be available again.
