Thanks for suggestions! Subtractive Arrangement is pretty much what I was looking for.
About creativity it's true, I don't like complicated beats, sometimes the less time you spend on it the better it sounds - just hop in, find the right drums, add some lead and background pad. Arpeggiator does wonders too, but it's not working all the time. Also Logic Pro default samples are perfect for instant creativity, but sometimes I feel kinda guilty for using them, because it's too easy, just drag and drop, it's usually when my beat is made only with samples - hard to really call it my own, but if you are vibing to it then it's kinda fine right? Most people don't care how the song is made, if it sounds good then it's good. But still I get more satisfaction when I am just jamming and messing around,.
