This question probably pops up about twice a year. Let me use an analogy to say what I want to convey.

I am sure at some point you have watched NHL hockey. Now when you watch a hockey game, how long after the initial puck drop do you start to focus on the passing, hitting, scoring, goaltending, fighting.... It is easy to forget that you are watching the greatest skaters in the world because very quickly the skating becomes subliminal.

Just like in PG software, the fact that it writes backing tracks and allows you to generate solos seems to become subliminal as people start to focus on the DAW aspects. You can change to Reaper, Sonar, Cubase, Logic, Ableton, Pro Tools..... and any of the what, 2 dozen DAWs out there, and not one of them is going to write your tracks for you. Unless you have drums (and know how to play them), keyboards (and know how to play them), guitars (and know how to play them), you can sit there and stare at a Pro Tools or a Reaper screen for days and still have nothing to mix.

Just like the skating in hockey, the writing of backing tracks quickly becomes subliminal and the concept of "THIS is what we meant for this thing to do" gets lost in the DAW-ness.
