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)
