Lexi, Well, I don't even know what Cakewalk you are using. But, you have to create a song title first, create a track for different instruments/vocal, choose a file you want to drop into the track that you want to listen to, make sure you line everything up the way you want it in the song. You can listen to each track separately or all together. It might be best that before trying to create music and editing to get the book out and take the time to go through the software step by step first. You can also go into one of the Cakewalk Forum instructional threads )based on what Cakewalk version you are using. Just click on all forums above, and match up your version and go into those forums. Thanks for listening.
Peace be with you. Blessings, John
