Memory Locations have many uses beyond marking points on your Session timeline, and in particular, are a great way to customise different track views that you can jump to quickly.
To create a new Memory Location, choose a number and then do one of two things depending which option you have selected in Numeric Pad Mode in the Operations tab of Pro Tools Preferences. If you have Classic selected, as I do, then to create a Memory Location, type a number then press Enter, both on the numeric keypad rather than the main keyboard; for instance, pressing ’9′ followed by Enter will create a Memory Location numbered 9.
Alternatively, if you have Transport selected as your Numeric Pad Mode, type ‘.’ (full stop), then a number, then Enter — again, all on the numeric keypad. Either way, a New Memory Location window will open. Choose None under Time Properties, then give it a Name. Then tick the Pre/Post Roll box so this particular Memory Location will remember that and nothing else. You can also add any comments you want, before finally clicking OK to store the Location.
Now, when I recall Memory Location 9 it changes the pre-roll and post-roll settings to what I had selected. You can recall a Memory Location by typing the number followed by ‘.’ (full stop) if you are in Classic mode, or ‘.’ then the number, then another ‘.’ if you are in Transport mode. Alternatively you can select your chosen Memory Location by clicking on it in the Memory Locations window. Note that if you hover the mouse, the Comments info appears in a separate floating box!
There are up to 200 Memory Locations available, and they can be used for saving settings for all sorts of things including Track Heights, Track Show/Hide combinations and Zoom settings.
So take some time and create some memory location points that do anythng but remember where you are on the timeline.
