Returns the note trackers used for this layout. Lume will call this method first when building a layout. For simple layouts, this method will only return a single note tracker with no filter.
NoteTracker objects are processed separately from the other components as Lume needs direct access to the trackers to update them when processing the MIDI file.
Symmez is a simple, abstract layout. It renders hollow diamonds for each currently active note. The name is derived from the musician of the same name, who was the predominant inspiration for Lume.
