Fellow dinosaur here, though "only" 38 years old. Googling "64th notes in Cakewalk staff view" brought me here. Cakewalk was a magical software for me when I was younger, and I especially loved composing in midi in Staff View, since I know to read music decently. Now I've discovered that Cakewalk is free (which is great!) but I felt that I missed higher resolution notes in the staff. Didn't there use to be at least up to 64th notes in older Cakewalks? Anyway, great thread! Guess I'll check out Reaper's notation as well, even though I've never quite found anything as good as Cakewalk :) Cheers!
