Definitions
Tie — An input-to-output connection.
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.
Front Panel Controls
Input and output buttons select inputs and
outputs. Output buttons light amber to
