Determines the tempo used to play a MIDI clip.
Hierarchy-the tempo is obtained from the time settings of the clip’s ancestors.
File-the tempo is obtained from the clip’s original MIDI file.
Note that this setting is used when creating a MIDI clip to determine its duration. Changing this field after the clip is created changes the tempo used to interpret the clip, but does not change the clip’s duration. To change a MIDI clip’s duration, use the clip handles.
Default value: Hierarchy
