CONST_DMUS_CURVES

Members of the CONST_DMUS_CURVES enumeration are used to define the shape of a curve in the DMUS_CURVE_PMSG type.

Enum CONST_DMUS_CURVES
    DMUS_CURVES_EXP =     2 
    DMUS_CURVES_INSTANT = 1 
    DMUS_CURVES_LINEAR =  0 
    DMUS_CURVES_LOG =     3 
    DMUS_CURVES_SINE =    4 
End Enum
DMUS_CURVES_EXP
Exponential curve shape.
DMUS_CURVES_INSTANT
Instant curve shape (beginning and end of curve happen at essentially the same time).
DMUS_CURVES_LINEAR
Linear curve shape.
DMUS_CURVES_LOG
Logarithmic curve shape.
DMUS_CURVES_SINE
Sine curve shape.
