you might want to graduate to CD+G form of karoke ... it uses Mp3 songs and adds lyrics and sounds 1,000 times better then the midi type!
I understand many use them to load in our keyboards ... but ... I figured I would use laptop to play them and use the arranger to do my tunes!
I couldn't go back to midi type karaokie or even Midi tunes anymore! It all sounds like carnival or circus music to me after the MP3 versions! They take the real band versions and DEvoice them and add lyrics .
Winamp has a cd+g add-on for it ...
I'm just giving a different slant of the kar./midi songs (that we don't use as arrangements)
