Does anybody know where can i get a sort of Kar files white paper?
My project is to create a program that could convert a kar file into a mpeg (suitable for playing in a home dvd player)...
An open source karaoke player whould also do...

Well, first you need to make a midi parser. A text or lyric event has a certain place in the midifile.

To know the exact timing of your text string, you need to calculate the midiclock (or tick) length by reading the tempo data and to devide this by the sequencer resolution (ppqn). Then just count the pulses, by adding all previous delta times together. Remember, delta times are in variable lenght format. Then multiply the number of pulses with the pulse lenght.

If you have extracted the lyrics with their timing, you could embed them as ID3v2 tags or as Lyrics3v2 tags in an MP3 file.
