I'm skeptical there are very many good ones (by my subjective taste) who use that approach. I suspect many of those people still use their computer keyboards as a way of entering notes in real-time, in which case you are still basically playing an instrument, with your computer keyboard acting as a MIDI keyboard. I also don't really think there's any software that "handholds" or "guides" you in the way you're describing. Can you give an example? If it's a drum machine, you still have to program the patterns yourself, for example. Your DAW won't structure your tracks for you.
