As I've written here before, I'll qualify my review by saying I've used Logic in various forms all the way back to the C-Lab days in the early 90's in some form or the other. Since Apple has purchased Logic from Emagic, it has become a lesson in efficiency and design. Never the simple program, Logic has layers and layers of functionality that require years to master.
Until now.
With this one book, the author fills the void that has heretofore been missing for us Logic users wanting to go "the extra mile" with our productions and knowledge.
I purchase and evaluate every single book on Logic, as I teach several courses on recording, mixing, mastering, and production, using various methods. My main program is Logic, even though I had gone through a brief Pro Tools phase (because everyone else was doing it---not a "mistake", but I feel the name "Pro Tools" misleads too many into thinking that it is the "best"---their marketing certainly is).
Succinctly, just let me say if you're a Logic user, you need this book. No matter how advanced: you need this book. If you're a beginner, go through the first volume, then get this book.
Kudos to the authors, and Kudos to Apple for evolving and maintaining such a fantastic and downright magical piece of software. This book helps to unlock "the next layer".
