   9  IPlugChunks - an example of storing data in chunks, and custom IControl classes
  10
  11  A step sequenced volume control / tarnce gate
  12
  13  Using chunks allows you to store arbitary data (e.g. a hidden, non-automatable parameter, a filepath etc) in the plugin's state,
  14  i.e. when you save a preset to a file or when you save the project in your host
  15
  16  You need to override SerializeState / UnserializeState and set PLUG_DOES_STATE_CHUNKS 1 in resource.h
  17
  18  // WARNING - I'm not happy with how the multislider data is shared with the high priority thread
  19  // need to rethink that
