I am not sure how familiar you are with notation, but you might wanna consider Dorico, it is focused more on writing than on production bus still has a lot of features to make it sound pleasant (as opposed to other notation programs like Finale or Sibelius.) It is a sort of notation program / DAW hybrid that I think is a really interesting crossover / niche. Another suggestion might be to check out Synfire. (I have no experience with Synfire though, yet)

Another great Iggy Pop story is the hilarious way in which his rider was written: http://www.iggypop.org/stoogesrider.html
