I had trouble with Lyrics.lua as it only read the midi Lyrics and not the other Text that most midi karaoke uses so I added a choice
1 = Text
2 = Copyright
3 = Sequence/Track Name
4 = Instrument
5 = Lyric
6 = Marker
7 = Cue
8 = Program
9 = Device
this will copy any to the midi Lyrics that the script will then read.
right click Save Link/Target As
lyrics multi.lua
Choose the midi Lyrics source
choose the track
choose beat (.25 works best to show all)
use mouse scroll + ctrl to zoom.
