Creates a AudioParameterBool with the specified parameters.
parameterID | The parameter ID to use |
parameterName | The parameter name to use |
defaultValue | The default value |
parameterLabel | An optional label for the parameter's value |
stringFromBool | An optional lambda function that converts a bool value to a string with a maximum length. This may be used by hosts to display the parameter's value. |
boolFromString | An optional lambda function that parses a string and converts it into a bool value. Some hosts use this to allow users to type in parameter values. |
