I have been trying to find some detailed info on how lyrics can be encoded into midi/kar files.
The best resource I found was: https://www.mixagesoftware.com/en/midikit/help/HTML/karaoke_formats.html

But it does not specify behavior when stuff is at same tick or what tags like @W, |C:| or [P2] means. I kinda figured out most of it on my own, but it would still be nice to have access to some complete specs of the different kar formats. I tried internet archive also.
