Track Form

The track form contains information about a single track. It can be embedded in a Segment Form or stored in its own file.

<DMTK-form> -> RIFF( 'DMTK'
  <trkh-ck>
  [<trkx-ck>]   // Optional track flags.
  [<guid-ck>]   // GUID for track object instance.
  [<vers-ck>]   // Version information.
  [<UNFO-list>] // Name, author, copyright information, comments.
  [<data>]    // Track data. 
)

<trkh-ck>

The first chunk contains the basic header information for a track.

<trkh-ck> -> trkh( <DMUS_IO_TRACK_HEADER> )

<trkx-ck>

This optional chunk contains flags for the track.

<trkx-ck> -> trkx( <DMUS_IO_TRACK_EXTRAS_HEADER> )

<guid-ck>, <vers-ck>, <UNFO-list>

For information on these three chunks, see Common Chunks.
