Karaoke RIP/KeyChange/Burn CD+G

[tomctucker]

1. I currently download CD+G songs from CD to my hard drive using.chemas-microsoft-com:office:office
2. Then successfully play each song.
3. I need to change the ???
4. I then want to "burn" the song (with modified key) to a CD+G CD so that I can insert into an external Karaoke player.

Can anyone help me understand if I can actually do steps 3 and 4 above? If so, what special products or instructions should I obtain?

Thanks for your help.
