+To help you know which bank is active (or even that you have a MIDI
+controller connected at all), the currently mapped controller have
+a green **activity highlight**. When you switch banks, the highlight
+also updates—a controller is only highlighted if its mapping is
+active in the currently selected bank. This way, it is easy to see
+which controllers are currently controllable by MIDI, and which ones
+that are not.
