In our tests, Ventura has been compatible with all of our supported* plug-ins.
There have been some reports of external drives using formats like exFAT not working to use as the install path for sounds in some of our installers. Updating to the latest version of Ventura has fixed the issue in those cases.
We would still recommend inquiring with companies that are developing the DAW that you use about compatibility before upgrading to make sure that the DAW is compatible.
* Products that still are available for purchase at toontrack.com, and not discontinued products.
