Fx protocol defines the host application’s methods that allow plug-ins to set and retrieve keyframes for the parameters they have.
- FxPlug 3.1+
Fx plug-ins can query the host application to find out whether keyframes exist and if so, how many there are, what times they are placed at, and what values parameters have at those keyframes. It also allows plug-ins to create new keyframes with the desired value at any given time.
This protocol was introduced in FxPlug SDK 2.0.
