The PowerTraks program is similiar to Cakewalk and Sonar not as complicated but also no where as powerful. It can do a lot things such as recording, midi and vocal harmony. As stated in one of the post you may not get what you are looking for in harmony but there are parameters and slide controls to change the sound and shape of what you are doing. There are also guitar programs that can add harmony. Not really sure what all you doing. This PowerTraks cost around 60 dollars. Which is not bad. The lowest Cakewalk is 100 dollars. Pray, may God bless you in your endeavors.
