I could not get it to work, in the Mac Manual Page 188 states:
"The popular Karaoke file format (.KAR) can be opened directly into Band-in-a-Box just like MIDI files. Chord
symbols are displayed (Band-in-a-Box intelligently analyzes the chords of the song), as well as the lyrics from the
Karaoke files.
"

Will try another way and let you know.
