Chord Track List

The chord track list contains chord data for a Track Form. It is organized as follows:

<cord-list> -> LIST( 'cord'
    <crdh-ck>       // Header
    <crdb-ck>       // Chord body chunk
    )
 

The subchunks are as follows:

<crdh-ck> -> crdh ( <DWORD> )
 

The header is a DWORD containing the chord root in the upper 8 bits and the scale in the lower 24 bits. For an explanation of what these bits represent, see DMUS_IO_SUBCHORD.

The body of data for the chord track list consists of information about a chord change and the component subchords:

<crdb-ck> -> crdb(
    <DWORD>           // size of DMUS_IO_CHORD
    <DMUS_IO_CHORD>
    <DWORD>           // number of subchords
    <DWORD>           // size of DMUS_IO_SUBCHORD
    <DMUS_IO_SUBCHORD>...
    )
