If you are looking for software that has tons of features and is user friendly at the same time, go with Cakewalk's Sonar. You'll be able to do anything you need to with this one. If you need, you can even import video into the program so you can synch up your music to the video. Has audio and MIDI capabilities (bare essentials in composing nowadays). With some practice (and a little patience) you'll be able to make your compositions sound professionally recorded, mixed, mastered, and produced.
