  VERSION HISTORY:
  2017-03-01 0.0 allenh - In the beginning...
  2017-03-04 0.1 allenh - Renaming volume(), adding setVolumeMax().
  2017-03-06 0.2 allenh - Renaming to playHandler().

  TODO:
  1. Note 0 is used for off, but since we can't play anything that low
     anyway, it's not a big deal. But, it would be nice to make the notes
     be 1-88 (base 1) instead of 0-87 (base 0).
