Modern production tools have mostly settled on the combination of pianoroll, automation curves, and visual placement of samples on the project timeline. That's great for some types of music, but becomes really awkward in other cases. As a basic example, making a breakbeat sequence makes pretty much no sense with the above interface, but is perfectly represented by the "series of commands" approach of a tracker. I frequently go back to Buzz for that kind of thing (and was happy to see it mentioned in the video).
