Is there any software for making your own music on pc. I am very interested in knowing if you software that will let you change or enhance recorded music.

Say I want to make my own version of a song and could change that song with software, using the song for tempo and note and then making my own version of that song from it.

I know there is ringtone software that will do this but want something much more creative than that.

"acid pro" and i think "cubase" also...dont ask me how to do it though. it confuses the hell out of me. then again its made for professionals. which im not.

Programs like Acid and Cubase are for creating original music. Acid is a loop based program with extensive loop libraries. Cubase is a full system of sequencers, sound modules, multitrack recording, etc...

I am not sure about what you are looking for. Maybe something like Adobe Audition (formerly CoolEdit) could do what you are looking for. I have used CoolEdit to change tempo while maintaining key on a particular song but you only have control over the stereo channels.

If you want a relatively easy program to create original music I strongly recommend the latest version of Band in a Box, Cakewalk Sonar, or Reason.
