If you are just going to execute this as a cue in a cue list then you don't need MIDI or hotkey triggers. (and in any case ESC and the MIDI you set for panic all in settings /MIDI Controls could take care of that anyway)
one scenario where it can be useful to use this with triggers is to set your default panic to 0 , and keys 1-9 to different panic times by having different 'fade & stop ALL over time X" settings in the triggers tab for each memo cue these keys hotkey trigger.
