typedef struct _DMUS_IO_STYLECURVE {
    MUSIC_TIME  mtGridStart;
    DWORD       dwVariation;
    MUSIC_TIME  mtDuration;
    MUSIC_TIME  mtResetDuration;
    short       nTimeOffset;
    short       nStartValue;
    short       nEndValue;
    short       nResetValue; 
    BYTE        bEventType;

    BYTE        bCCData;
    BYTE        bFlags;
} DMUS_IO_STYLECURVE;

mtGridStart

Start time of the grid in which the curve occurs.

dwVariation

Variations that this curve belongs to. Each bit corresponds to one of 32 variations.

mtDuration

Duration of the curve.

mtResetDuration

How long after the curve is finished until the reset value is set.

nTimeOffset

Offset from mtGridStart at which the curve occurs.

nStartValue

Start value.

nEndValue

End value.

nResetValue

Reset value, set after mtResetDuration or upon a flush or invalidation.

bEventType

Type of curve. See DMUS_IO_CURVE_ITEM.

bCurveShape

Shape of curve. See DMUS_IO_CURVE_ITEM.

bCCData

CC number if this is a control change type.

bFlags

Set to DMUS_CURVE_RESET if the nResetValue must be set when the time is reached or an invalidation occurs because of a transition. If 0, the curve stays permanently at the new value. All other bits are reserved.
