This callback method is called by the AudioProcessorValueTreeState when a parameter changes.

Within this call, retrieving the value of the parameter that has changed via the getRawParameterValue() or getParameter() methods is not guaranteed to return the up-to-date value. If you need this you should instead use the newValue parameter.
