You go into a restaurant. There's a menu with a whole bunch of entrees. You choose one, you like it, and next time you come back to the restaurant, you try a different entree...maybe. Or maybe you liked the first one so much, you order it again. But I'm pretty sure that no matter which restaurant you like, you've not tried EVERYTHING on the menu
One of SONAR's strengths, and the reason why I use it, is because it can handle a huge variety of tasks. Some updates, features, and content are relevant only to particular workflows or styles of music. If they don't relate to you, it's not necessary to learn them.
Remember, all that matters is the emotional impact of your music on your listeners...and the personal process of self-discovery. SONAR may give you a massive number of tools, but you don't
need all of them. Choose the ones you want...then make compelling music so you can help change the world.
P.S. Theoretically, my car can go up to 140 MPH, but I've never taken it over 90...same principle
