Set of ties — An input tied to 2 or more outputs.

Configuration — One or more ties or sets of ties.

Current configuration — The currently active configuration (also called configuration 0).

Global preset — A configuration that has been stored. One global preset can be assigned to each input button. When a global preset is retrieved from memory, it becomes the current configuration.
