anchor.diff:  As noted above, cues can also be configured to take advantage of the
   pressure sensitivity of the Launchpad Pro cue pads, so that as you
   vary the pressure with which you are holding down the pad, some

  running, and can optionally display
  <<mapping_sync#metronome-control,metronome>> information as well. If a
  cue was defined with adjustable parameters for its effect, they will
  also be displayed in the text area, and you will be able to

  above the parameter.
  
  The rightmost encoder, past the text area, adjusts the show Grand

  variables, `chance` and `Fade`, which can be adjusted by turning the
  encoders above them. The `chance` value is changing rapidly because it
  is configured to also be adjusted through the pressure sensitive cue
  pad that was used to launch it.
