I can't imagine why I would ever want another DAW. I've used CW software since tape.
The thought of not being able to open old songs is not an option so cross grading is not for me.
As for extra goodies I have to pay for I can't imagine what I might want unless they can do or license believable virtual lyrics and midi to vocals.
I'd pay for that. Don't link realivox, I know.
I've got Jamstix, but that is the kind of software that would be a pretty cool add-on for most users as programming drums is a nightmare for many users. Logic is the only program I know of that has something similar, though not as full featured.
I'd think most of the other upgrade ideas I can think of would be a part of the core program (such as some quick arranging functions, perhaps similar to what EZKeys can do but with better integration.
