Ardour 3.0 splits preferences into two sections:
- Settings that should logically apply to all sessions, because they are based on user workflow or system configuration
- Settings that are per session, because they depend or reflect session content or design
There are two separate (but similarly designed) dialogs, one under Session -> Properties for the second category and Edit -> Preferences for the first. Each window uses tabs to group a set of preferences, and is generally much better laid out, more logically presented and simpler to use than its 2.X equivalent. Representative tabs from each dialog are shown below:
