• when the audio file is reloaded for playback, recall the metadata defining the plurality of different playback loops from the audio file;
• and
• enable control of the plurality of different playback loops during a subsequent playback of the audio file by associating the metadata defining each one of the plurality of different playback loops with a different one of the plurality of loop buttons.
