Detailed Description

MIDI Meta Event structure one per Meta Event. MIDI Meta Events are like audio metadata, except that they are interspersed with the MIDI content throughout the file and are not localized in the header. As such, it is necessary to retrieve information about these Meta Events from the engine, as it encounters these Meta Events within the MIDI content. For example, SMF files can have up to 14 types of MIDI Meta Events (copyright, author, default tempo, etc.) scattered throughout the file.
