Members

mtGridStart

Start time of the grid in which the curve occurs.

dwVariation

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

mtDuration

How long the curve lasts.

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. The following types are defined:

DMUS_CURVET_PBCURVE
DMUS_CURVET_CCCURVE
DMUS_CURVET_MATCURVE
DMUS_CURVET_PATCURVE

bCurveShape

Shape of curve. The following shapes are defined:

DMUS_CURVES_LINEAR
DMUS_CURVES_INSTANT
DMUS_CURVES_EXP
DMUS_CURVES_LOG
DMUS_CURVES_SINE

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.
