This book contains the complete chapter 14 entitled "Groups" from my comprehensive 1,160 pages book "Pro Tools - 2020 - How it Works". If you are not familiar with my best-selling book series, "Graphically Enhanced Manuals", this will give you an idea of how I write manuals utilizing what I like to call a "visual approach to learning". In these books, you will find detailed information with lots of graphics and unique diagrams that you simply won't find anywhere else.
