  1. I want to create karaoke medleys. I DONT WANT the entire song….some songs I may only want the bridge and other song only the intro or the ending…meaning I would have to establish and entry and exit point for each song with a cross fade.
    Can it end up as playable MP4 video file?
    Thank you for your input and some possible sales

    • Sorry, at the moment the software does not allow to cut and merge pieces of songs. It allows to merge entire songs as they are, or convert them to other formats.

  2. I want to convert KFN to MP3+G, keeping unchanged the synchronized text,
    can I do that whit this editor.

    • You can convert KFN to MP3 Karaoke (with lyrics already synchhronized) and playable with Kanto Karaoke Player (
      Try to do some conversion from KFN to MP3 and then play the mp3 with Kanto Player to see also lyrics.

  3. I tried the trial version, but it failed as it asked for registration code…can you help

  4. Can this software “batch” convert an entire folder of KFN songs to MP3+G .. or do songs have to be converted one by one?

    • It support batch conversion too
