The chordmap track list contains data for a Track Form. It is organized as follows:
<pftr-list> -> LIST('pftr'
  <pfrf-list>...
  )
The data consists of one or more lists containing time stamps and references to chordmaps:
<pfrf-list> -> LIST('pfrf'
  <stmp-ck>
  <DMRF-list>
  )
The notation for the time stamp chunk is as follows:
<stmp-ck> -> stmp( <DWORD> )
For information on <DMRF-list>, see Reference List.
