I received my teletype last week. I think it’s definitely possible to do what you want with it, I can see a few way of programming it to do “traditional” sequences like you’re saying.
But I’d also say that if what you’re looking for is traditional sequencing this is not the most effective solution.
I really like it because of the “programming” workflow, and being able to mix generative and controlled sequencing.
Something good with this kind of tool is to try to understand what they can do instead of trying to fit an pre-conceived idea of it. Then see if that’s useful for you or not 
Check the docs and the studies (and just type studies too!), they are really well done and provide a good idea of capabilities.
