nParamIndex as Integer,
fValue as Single
) as enumErrorCodes

Parameter
|
Description
|
|
|
nPlayer
|
Number representing the zero-based index of the involved player
|
nIdVST
|
Unique identifier of the VST effect as returned by the VST.EffectLoad or VST.InstrumentLoad methods.
|
nProgramIndex
|
Zero-based index of the program
|
nParamIndex
|
Zero-based index of the parameter
|
fValue
|
The new value of the given parameter.
Values must be always in the range between 0.0 and 1.0, however, from the view of a VST effect, they may represent completely different values. In general, this value represents the ratio between the minimum and maximum values that the parameter could assume and not the "real" value of the parameter; if for example a certain parameter should have values inside the range 0-256, a value of 128 would be returned as 0.5.
