A Karaoke MIDI file combines MIDI musical instructions with karaoke data, such as song lyrics and their timing. Compatible software can play the accompaniment while displaying the lyrics for the singer.
The KRX format is an old format, so compatibility depends on the karaoke application used to open it. Standard MIDI players may not support the KRX extension or its karaoke data.
Open the file with the karaoke software that created it or with another application that supports Karaoke MIDI files. If the file does not open, it may require the original or a compatible karaoke program.
Standard MIDI players may not open KRX files because they may not support the format's karaoke information.
If compatible karaoke software can open the file, use its export or save-as options to create a format supported by that program. Lyric timing and other karaoke information may not be preserved during conversion.
