Having a topic about it is already quite something, I think the average producer/beatcreator being tied to a budgetsetup making logic a less logical purchase (though it would probably be the best move anyone can make).
Anyhow, maybe my neighbour here wants to start at the basics of logic lol explain how to create a screenset ...and why
screensets are created automatically in logic 7/7.2 buttons 1-9 on your keyboard move to screensets 1-9, and unless you select the "lock screenset" feature, what you do to a screenset before moving to another one becomes that screenset. in other words, if i open a huge arrange window in 1, press 2 to go to screen set 2, and open a mixer and an environment window in 2, and then go back to 1, it will be a huge arrange window, and if i go back to 2, it will have my mixer and environment (key thing to realize is that this is constant i.e. not just the first time you "edit" a screen, everytime you go to it and change something unless it is locked it will be saved as the new screen). you can setup up to 99 screensets per project; to access ones higher than 9, you hold down Option-Control and then press the number of what you want i.e. "12" for screenset 12. to get back to the original 9 you simply need to use 1-9, no option control necessary. also, next to the window menu in the top menu bar there is a number, often "1"- this number tells you what screenset you're currently looking at.
the purpose of these sets is that logic is a beast of a program; the arrange window isnt always appropriate to keep small even on a big monitor because when you open things like track automation, each track needs a good amount of space to be worked with with precision, and you also will typically have a number of tracks in your finished project. screensets are hands down the biggest thing missing from other sequencers; what i do is i set up a master screenset in 1 with a small version of every window, and then assign a huge arrange to 2, matrix editor to 3 (piano roll), hyper edit to 4, mixer to 5, and environment to 6. Also i'll often use 7-9 to open a huge matrix edit on a specific portion of the piano keys in the piano roll (i.e one showing C1-C3, etc) so that no matter where notes i'm trying to edit may fall I can access them with no scrolling, only one press of a button. bottom line they accelerate your workflow dramatically.
