DMUS_IO_CHORDMAP_SUBCHORD
The DMUS_IO_CHORDMAP_SUBCHORD structure contains information about a subchord. Used in the Chordmap Form.
Syntax
typedef struct _DMUS_IO_CHORDMAP_SUBCHORD {
DWORD dwChordPattern;
DWORD dwScalePattern;
DWORD dwInvertPattern;
BYTE bChordRoot;
BYTE bScaleRoot;
WORD wCFlags;
DWORD dwLevels;
} DMUS_IO_CHORDMAP_SUBCHORD;
Members
dwChordPattern
Notes in the subchord. Each of the lower 24 bits represents a semitone, starting with the root at the least significant bit, and the bit is set if the note is in the chord.
dwScalePattern
Notes in the scale. Each of the lower 24 bits represents a semitone, starting with the root at the least significant bit, and the bit is set if the note is in the scale.
dwInvertPattern
Points in the scale at which inversions can occur. Bits that are off signify that the notes in the interval cannot be inverted. Thus, the pattern 100001111111 indicates that inversions are allowed anywhere except between the fifth and seventh degrees of a major scale.
bChordRoot
Root of the subchord, where 0 is the lowest C in the range and 23 is the top B.
bScaleRoot
Root of the scale, where 0 is the lowest C in the range and 23 is the top B.
wCFlags
Reserved for future use.
dwLevels
Bit field showing which levels are supported by this subchord. Each part in a style is assigned a level, and this chord is used only for parts whose levels are contained in this member.
