\ingroup vstIHost vst310
- [host imp]

- [released: 3.1.0]
- [optional]

One part handles:
- Setting dirty state of the plug-in
- Requesting the host to open the editor

The other part handles parameter group editing from the plug-in UI. It wraps a set of \ref IComponentHandler::beginEdit /
\ref Steinberg::Vst::IComponentHandler::performEdit / \ref Steinberg::Vst::IComponentHandler::endEdit functions (see \ref IComponentHandler)
which should use the same timestamp in the host when writing automation.
This allows for better synchronizing of multiple parameter changes at once.

/** Extended host callback interface for an edit controller: Vst::IProgress
\ingroup vstIHost vst370
- [host imp]

- [released: 3.7.0]
- [optional]

Allows the plug-in to request the host to create a progress for some specific tasks which take
some time. The host can visualize the progress as read-only UI elements. For example,
after loading a project where a plug-in needs to load extra
data (e.g. samples) in a background thread, this enables the host to get and visualize the current status of the loading
progress and to inform the user when the loading is finished.
Note: During the progress, the host can unload the plug-in at any time. Make sure that the plug-in 
supports this use case.

/** MIDI Mapping interface: Vst::IMidiMapping
\ingroup vstIPlug vst301
- [plug imp]
- [extends IEditController]
- [released: 3.0.1]
- [optional]

MIDI controllers are not transmitted directly to a VST component. MIDI as hardware protocol has
restrictions that can be avoided in software. Controller data in particular come along with unclear
and often ignored semantics. On top of this they can interfere with regular parameter automation and
the host is unaware of what happens in the plug-in when passing MIDI controllers directly.

So any functionality that is to be controlled by MIDI controllers must be exported as regular parameter.
The host will transform incoming MIDI controller data using this interface and transmit them as regular
parameter change. This allows the host to automate them in the same way as other parameters.
CtrlNumber can be a typical MIDI controller value extended to some others values like pitchbend or
aftertouch (see \ref ControllerNumbers).
If the mapping has changed, the plug-in must call IComponentHandler::restartComponent (kMidiCCAssignmentChanged)
to inform the host about this change.
