Hi Steffan,

Download the great midi converter by Andy Gittings from: http://karasoft.free.fr/download.htm
It's so easy to use and it converts karaoke, midi type 0 and midi type 1 in all directions. Once a karaoke or midifile is loaded just press "Convert to SMF 0". If it is already a midi type 0, you'll be told so.
Regards, Ad.
