/** MIDI Learn Interface.
\ingroup vstIPlug vst3612
- [plug imp]
- [extends IEditController]
- [released: 3.6.12]
- [optional]
If this interface is implemented by the edit controller, the host will call this method whenever
there is live MIDI-CC input for the plug-in. This way the plug-in can change it's MIDI-CC parameter
mapping and inform the host via the IComponentHandler::restartComponent with the
kMidiCCAssignmentChanged flag.
Use this if you want to implement custom MIDI-Learn functionality in your plug-in.
