Plug-Ins may not load at all, or throw errors on load if BitWig's VST Cache contains a corrupted index.
This can sometimes happen if BitWig indexes a plug-in during installation.
These issues may be resolved by regenerating the VST Cache.
Please follow these steps:
1) Close BitWig Studio
2) Delete the following folder and file:
macOS:
The folder /Users/your_username/Library/Application Support/Bitwig/Bitwig Studio/index
The file /Users/your_username/Library/Caches/Bitwig/vst-metadata
Windows:
The folder C:\Users\your_username\AppData\Local\BitwigStudio\index
The File: C:\Users\your_username\AppData\Local\BitwigStudio\cache\vst-metadata
3) Open BitWig Studio again and allow it to re-index your plug-ins.
Please ensure that you have the latest versions of the iLok License Manager, your Synchro Arts products and your DAW installed.
