| **Automation vs. saving/restoring plugin state:** DAWs and plugins also use an unrelated //non-real-time// method of bi-directional communication scheme, to allow the DAW to save the entire //state// of each plugin as part of a recording project file, in order to later restore that state when the file is reopened for a later editing session. Although this is separate from automation, I consider this an important aspect of plugin parameter management which ought to be integrated into the parameter-handling code. In JUCE, state management is supported through the //getStateInformation()// and //setStateInformation()// methods of the //AudioProcessor// class. | **Automation vs. saving/restoring plugin state:** DAWs and plugins also use an unrelated //non-real-time// method of bi-directional communication scheme, to allow the DAW to save the entire //state// of each plugin as part of a recording project file, in order to later restore that state when the file is reopened for a later editing session.

| JUCE 5 provides two distinct sets of classes to support parameter automation via an older and a newer approach. The older approach, which pre-dates JUCE version 5, involves instantiating parameter objects based on classes derived from //AudioParameter//. The newer approach, based around an extensive new class called //AudioProcessorValueTreeState//, promises more streamlined code and integrated support for //undo/redo// operations. Unfortunately, neither approach is particularly well-documented, so I decided to investigate both myself. | JUCE 5 provides two distinct sets of classes to support parameter automation via an older and a newer approach.
