+ *
+ * There are two widely spread karaoke formats:
+ * - KMIDI (.kar), an inofficial midi extension by Tune 1000
+ * - Standard Midi files with lyric meta-tags (SMF with lyrics, .mid).
+ *
+ * KMIDI uses two tracks, the first just contains a header (mostly track 2) and
+ * the second the lyrics (track 3). It uses text meta tags for the lyrics.
+ * SMF uses just one track (normally track 1) and uses lyric meta tags for storage.
+ *
+ * Most files are in the KMIDI format. Some Midi files contain both lyric types.
