Detailed Description

Base class which deals with the "raw"/untyped parameter and keep the normalized value (ParamValue in the range [0.0,1.0]).

Also keeps the "previous" value which is the value the param had in the previous frame/call to process.

Member Function Documentation

addToOutput()

tresult addToOutput

(

ProcessData &

oData

)

Add the current normalized value as an output parameter changes.

getNormalizedValue()

ParamValue const & getNormalizedValue ( ) const

inline

getParamDef()

RawVstParamDef const * getParamDef ( ) const

inline

getParamID()

ParamID getParamID ( ) const

inline

getPreviousNormalizedValue()

ParamValue const & getPreviousNormalizedValue ( ) const

inline

hasChanged()

bool hasChanged ( ) const

inline

Returns

true if the parameter has changed within the frame (previous and current are different)

resetPreviousValue()

bool resetPreviousValue ( )

virtual

Called at the end of the frame so that previous value is set to current value for the next frame.

Returns

true if previous value was different than current value

Reimplemented in RTVstParameter< T >.

updateNormalizedValue()

bool updateNormalizedValue ( ParamValue iNormalizedValue )

virtual

Update the parameter with a new normalized value.

This is typically called after the VST parameter managed by the VST sdk changes (for example, moving a knob or loading a previously saved plugin)

Returns

true if the value was actually updated, false if it is the same

Reimplemented in RTVstParameter< T >.
