Listen to the MIDI songs online, using your computer's media player. This step is like an audition to select arrangements you like.

Download and install Karafun. The karaoke editor is automatically installed as well. It is free for personal use.
Start the Karafun karaoke editor. Go to "File," "New" and select "KFN Karaoke."
Set the background color in the "Properties" dialog box on the right if you do not wish to use a background image.
Set an image as background in the "Properties" dialogue box, if you prefer it instead of a solid color. When browsing for an image, the "Library" dialog box opens. Click the "Add" button to add the image to the library and then close the dialog box.
Click the "Library" icon on the tool bar and then click the "Add" button to browse and add a MIDI song as the karaoke audio source.

Click the "Record" button on the tool bar and answer "Yes" when asked if you are ready. The MIDI song will begin to play.
Press the space bar for each word in the song as you sing along softly. You should be familiar with the song for this step. A marker in the form of a dotted line appears at each synchronization point.
Double-click inside the horizontal time bar labeled "Vertical Text." A text box appears.
Enter the lyrics, one phrase at a time. Keep in mind that you want the lyrics to fit comfortably on the screen during playback. Press "OK" when finished. The words will appear in the vertical text area at the synchronization points you selected.
Go to "File," "Save" and then select the file extension ".kfn" when finished working on the file.
