Yes, exactly, but in context you meant multiple recursions. In my experience, to stay on the math note, with each added step there is exponential increase in expense. This is why I was surprised to hear you say.
Of course the suggestions you highlight are possible, but the workflow and processing time can make it a very consuming process; repeat ad-infinitum.
For example, as an exercise I thought to create some breaks completely on-board, sequence, sample, chop, resample, etc. Lots of work for eight bars. Not a wonderful solution and I didn't even include FX.
I think it is rather simplistic to say it's only a difference of workflow.
So, I come to the conclusion a workstation's usefulness is closely related to the type of music one is producing. Of course, it makes sense that most EDM, DnB, Glitch, Techno producers are not going to use a workstation for their productions. They already have the many tools needed for this music.
On the opposite spectrum, a classical composer, small band, or songwriter are a few good examples. I can completely understand they could find everything they need to create everything on workstation alone.
I believe that music and technology are intrinsically inseperable. That's what we are really getting at here, isn't it? It's not a new hypothesis and maybe only a discussion for the classroom and tea. In practice, the artists know what they need, use what they do, and make what they make - there really isn't a question at all.
Ok, now back to ∞ and beyond!
