Node Properties: parameter
The parameter node supports the following properties:
Basic Properties
index (required)
Type: unsigned int
The zero-based index of the plugin parameter.
name
Type: string
The name to display for this parameter instead of the default plugin parameter name.
valueMinimum
Type: int
The minimum value of this parameter.
valueMaximum
Type: int
The maximum value of this parameter.
valueDefault
Type: int
The default value of this parameter.
isIntRange
Type: bool
Set to true if the value range of this parameter is integer-based.
isToggle
Type: bool
Set to true if this parameter is a simple Off/On toggle. Implicitly sets valueMinimum, valueMaximum, and isIntRange.
valueTexts
Type: array of string
An array of strings representing the value texts for this parameter. Implicitly sets valueMinimum, valueMaximum, and isIntRange.
unit
Type: string
The unit of this parameter's value (e.g., "Hz", "dB").
Advanced Properties
matchedName
Type: string
The name of this parameter that should match the extracted parameter name if ParameterNames is set as matchingMode on the module.
quantizeDefault
Type: int
The default value of this parameter when the quantize mode is enabled.
quantizeMinimum
Type: int
The minimum value of this parameter when the quantize mode is enabled.
quantizeMaximum
Type: int
The maximum value of this parameter when the quantize mode is enabled.
hide
Type: bool
Set to true to hide a parameter. Useful when using a matchingMode that requires all parameters to be present in a module for detection purposes but some of these parameters are actually unused.
unusedIf
Type: string (math expression)
A math expression that evaluates whether this parameter is unused. Use p10 to refer to the value of the parameter at index 10. If no matchingMode is defined for this module, p10 evaluates the global parameter index. If a matchingMode is defined, p10 refers to the parameter index relative to the module's first parameter. If the expression evaluates to 1.0, the parameter is considered unused (it will be greyed out and stop displaying a parameter value on the E1).
hideIfUnused
Type: bool
Set to true to hide a parameter that is considered unused (via the unusedIf property) instead of displaying it as greyed out.
valueExpression
Type: string
A mathematical expression to convert a plugin's normalized parameter value (ranging from 0.0 to 1.0) into a more meaningful value (e.g., from 20 Hz to 20,000 Hz). This is especially useful for plugins that don't report their parameter values in meaningful units, such as those in Reason Rack or VCV Rack.
The current normalized parameter value from the plugin is represented by the variable x. For example, to map a normalized parameter to a range of -20 to 20, the expression can be written as (x * 40) - 20.
formattingProfile
Type: string (key)
A string that matches an existing formatting profile which will be used to format the result of a value expression.
unitConversionProfiles
Type: array of string
An array of unit conversion profiles that will be applied to this value expression.
