Track Position Numbers Stay with Hidden Tracks
When selected, tracks keep their track numbers even when hidden. When not selected, numbers are only assigned to tracks that are shown. In this case, shown tracks are then numbered sequentially, and hidden tracks are not numbered.
Tool Tips Display Options
Function
Configures Tool Tips to show the basic function of the item.
Details
Configures Tool Tips to show the complete form of an abbreviated name or item (such as a track name). Details view can also show the hidden or abbreviated value of parameters, as well as input and output assignments.
Edit Window Default Length
This preference sets a default length for the Edit window in hours, minutes, seconds, and frames (Pro Tools HD and Pro Tools with Complete Production Toolkit only). This is useful if you want to assemble a session of a particular length or leave extra room to expand the Edit window’s work area in your session. The maximum length is 24 hours. For best scrollbar sensitivity, set the length to slightly longer (a minute or more) than the total session or song length.
“Organize Plug-In Menus By” Options
These options customize how plug-in menus are organized in the Insert selector or Plug-In selector.
Flat List
Organizes plug-ins in a single list, in alphabetical order.
Category
Organizes plug-ins by process category (such as EQ, Dynamics, and Delay), with individual plug-ins listed in the category submenus. Plug-Ins that do not fit into a standard category (such as the Signal Generator), or third-party plug-ins that have not had a category designated by their developers, appear in the Other category. Plug-Ins can appear in more than one category.
Manufacturer
Organizes plug-ins by their manufacturer (such as Bomb Factory, Focusrite, or TL Labs), with individual plug-ins listed in the manufacturer submenus. Plug-Ins that do not have a Manufacturer defined will appear in the “Other” manufacturer folder.
Category and Manufacturer
Organizes plug-ins in two levels of menus. The top menus display plug-ins by process category (such as EQ, Dynamics, and Delay), with individual plug-ins listed in the category submenus. The bottom menus display plug-ins by manufacturer (such as Bomb Factory, Focusrite, or TL Labs), with individual plug-ins listed in the manufacturer submenus.
Language Options (Windows Only)
You must have Administrator privileges for the Pro Tools application Properties to change these options.
Language
Sets the language to use in the Pro Tools application, independently of what language version of Windows is used.
Default Automatic Naming to English
Causes automatically named session elements in a session to be named in English even when working with the Pro Tools application set to another language.
Auto-Switch Input Language
When the Auto-Switch Input Language option is enabled, the input language is switched automatically from English to the current OS input language when entering text. It automatically switches back to English for using Keyboard commands in Pro Tools. When disabled, English is used when entering text regardless of the current OS input language.
