DMUS_IO_PARTREF

The DMUS_IO_PARTREF structure contains information about a part reference. It is used in the Style Form.

typedef struct _DMUS_IO_PARTREF {
    GUID  guidPartID;
    WORD  wLogicalPartID;
    BYTE  bVariationLockID;
    BYTE  bSubChordLevel;
    BYTE  bPriority;
    BYTE  bRandomVariation; 
} DMUS_IO_PARTREF;

guidPartID

Identifier of the part.

wLogicalPartID

Identifier corresponding to a particular MIDI channel on a port.

bVariationLockID

Parts with the same value in this member always play the same variation.

bSubChordLevel

Subchord level that this part wants. See Remarks.

bPriority

Priority of the part. For information on priorities, see Channels.

bRandomVariation

When set, matching variations play in random order. When clear, matching variations play sequentially.

Remarks

The bSubChordLevel member contains a zero-based index value. At run time, 1 is shifted left by this value to yield a 1-bit value for comparison with the dwLevels member of a DMUS_SUBCHORD structure. Thus, a part with a bSubChordLevel of 0 would be mapped to any subchord that contained 1 in dwLevels.
