Track containers

What is a track container?

A track container(class TrackContainer) is a group of several tracks. There are three types of track containers:

• Song container(part of Song): The root track container

• Pattern store(PatternStore): The container for tracks in patterns

• Preview track container(PreviewTrackContainer): The container for tracks used in previewing presets

Things you can do with it

• TrackContainer::tracks(): Get the list of all tracks in the container.

• TrackContainer::addTrack(Track *): Add a track to the track container. You don't need to call it in most cases because Track::create will add the created track to the given container.

• TrackContainer::removeTrack(Track *): Remove a track from the track container.

Accessing to track containers

You can access to Song and PatternStore via Engine. You can't access PreviewTrackContainer directly because it's intended to be used only by PresetPreviewPlayHandle.
