   You can activate any cue shown by pressing its pad; running cues will
   light up, and darken again when they end. If the cues are configured
  -to respond to velocity, you can adjust the corresponding parameters by
  +to respond to velocity, you can adjust the corresponding variables by
   how hard you are pressing on the pad while the cue is running.
   
   To stop a running cue, press its pad again. Some cues will end

  ==== Numeric Cue Variables
  
  If the cue that created an effect has numeric parameters assigned to
  it, the parameter names and values will appear above the effect name,
  and they can be adjusted using the encoder knob above the parameter.
  For example, in addition to varying the sparkle `chance` parameter
  using the pad pressure, as was done above, its `Fade` parameter can be
  adjusted using the effect parameter encoder above it. As soon as you
  touch the encode knob associated with a parameter, a graphical
  representation of the current value replaces its name, and updates as
  you turn the encoder to change the value.

  If an effect has only one adjustable parameter, it will take up the
  entire effect area, and you can use either encoder to adjust it, as
  when adjusting a Focus <<cues#creating-function-cues,function cue>>
  for the Torrent moving head spot:

  When you release the encoder knob, the adjustment graph disappears,
  and the variable name reappears.
