The Core version of Studio Strings features a standard (8, 6, 6, 6, 4) player setup, with access to the default Tree microphone position. With Professional, you have access to 7 extra unique microphone positions, a large band section (16, 12, 12, 12, 4) and 2 divisi sections (4, 3, 3, 3), on top of what is offered in the Core version. You can use these divisi options to create a chamber section, or even layer them with larger sections.
