Fx protocol defines the methods the host application provides to set a plug-in’s parameter values.
- FxPlug 3.1+
This is version 3 of the
Fx protocol. This protocol was introduced in FxPlug SDK 2.0.
A plug-in that doesn't need the new functionality found in version 3 should simply conform to the version 1 or 2 protocol. This will ensure compatibility with older plug-in hosts that might not support version 3.
