In addition, you are granted the "VCV Rack Non-Commercial Plugin License Exception", allowed under section 7 of GPLv3, and a commercial licensing option.
A Plugin is defined as a software library intended to be linked and executed by this software.
You are granted the permission to use this software's Application Programming Interface (API) in your Plugin in source and binary forms, as well as link to this software with the Plugin, regardless of the Plugin's license terms even if it would otherwise violate the terms of this software's GPLv3, provided that the Plugin is distributed free of charge.
Derived works of this software may keep or omit this Exception.
This means that non-commercial plugins do not need to be licensed under the GPLv3 and can be released under any license of your choice (e.g. open-source or proprietary freeware). However, plugins that copy a significant portion of non-API source code from Rack must be licensed under GPLv3.
If you wish to release a proprietary commercial plugin, email support@vcvrack.com for commercial licensing. A commercial license is included for plugins sold on the VCV Library.
Licenses of third-party libraries are listed in LICENSE-dist (HTML).
