Panel Operation
All Ross® switcher control panels operate on the same basic principles for assigning a row to an ME and selecting sources on the buses of that ME.
Keying
Keying is the term used to describe when you insert (or electronically cut) portions of one scene into another, or place titles over background images. Keys are made up of two basic components, an alpha, that cuts the hole in the background video, and a fill, that fills the hole with different video.

Panel Operation
All Ross® switcher control panels operate on the same basic principles for assigning a row to an ME and selecting sources on the buses of that ME.
- Bus Assignment
  Each row on the panel can be assigned to a different ME or resource of the switcher. How the row is assigned to the resource depends on the model of control panel you have.
- Video Sources
  The switcher has access to three basic types of video sources, external, internal, and follows.
- Transitions
  Transitions are used to change the background video and take keys on and off-air. A transition can include any combinations of background and keyers for an ME, MiniME™, or MultiScreen. The background and each keyer can be transitioned independently.

  - To Set Up a Key on TouchDrive
    The TouchDrive control panel has a dedicated Keyers area that allows you to quickly assign the key bus to a keyer, transition the key on or off-air, and see the status and configuration of each key on the ME.
  - To Set Up a Key on Carbonite Black
    The Carbonite Black control panel allows you to quickly select a key type and video source for a key. The DashBoard menus follow your selection to allow easy setup of the key.
- Memories
  A memory register is a snapshot of the current state of the switcher that can include one or multiple resources of the switcher.
- Custom Controls
  Custom controls record actions on the switcher. This allows you to create repeatable macros that can be used to automate some tasks.
- Panel Shortcuts
  There are a number of button combinations that allow you to reset, copy, or swap configurations.
