positive.code: corresponding controller pad is held down (this is done by passing a
  true value with the `:held` optional keyword argument when creating
  the cue). This is often done for intense effects like strobes.
  Currently, only physical controllers, not the web interface, honor the
  `:held` flag, since with the web interface only one cell can be
  clicked at a time. (This will be easy to change if there is demand for
  it.)
  
  Cues can also offer pressure sensitivity on controllers which support
  this (like the Ableton Push). For such cues, one or more variable used
