Parameter Attributes
Order
Sets the order of recall of this parameter. Lower numbers are recalled first. The order of recall of parameters with the same order number is undefined.
Parameter Mode Enable
Parameter Mode Enable (not available from Parameters window)
Link to Scripting Name
When checked, the Scripting Name is linked to the Long Name attribute.
Long Name
The long name of the parameter. This name must be unique per patcher hierarchy.
Short Name
Sets the short name for the object's visual display. The maximum length varies according to letter width, but is generally in a range of 5 to 7 characters.
Type
Specifies the data type. The data types used in Max for Live are:
Float
Int
Enum (enumerated list)
Blob
Note: By convention, the Live application uses floating point numbers for its calculations; the native integer representation is limited to a range of 0-255 (similar to the char data type used in Jitter). When working with Live UI objects whose integer values are likely to be outside of the 0-255 range, the Type attribute should be set to Float, and the Unit Style attribute should be set to Int.
Range/Enum
When used with an integer or floating point data type, this field is used to specify the minimum and maximum values of the parameter.
When used with an enumerated list (Enum) data type, this field contains a space-delimited list of the enumerated values (if list items contain a space or special characters, the name should be enclosed in double quotes).
Modulation Mode
Sets the Modulation Mode used by the Live application. The modulation modes are:
None
Unipolar
Bipolar
Additive
Absolute
Modulation Range
This parameter is only used with the Absolute modulation mode. It specifies defines the range of values used.
Initial Enable
When checked (set to 1), the UI object can store an initialization value. The value is set using the Initial attribute (see below).
Initial
Sets the initial value to be stored and used when the Initial Enable attribute is checked.
Unit Style
Sets the unit style to be used when displaying values. The unit style values are: Int: displays integer values
Float: displays floating point values
Time: displays time values in milliseconds (ms)
Hertz: displays frequency values (Hz/kHz).
deciBel: displays loudness (dB)
%: Percentage
Pan: displays Left and Right values
Semitones: displays steps (st)
MIDI: displays pitch corresponding to the MIDI note number
Custom: displays custom data type
Native: defaults to floating point values
Custom Units
Sets the units to be used with the 'Custom' unit style (see "Unit Style", above). Custom unit strings may be simple symbols (e.g. "Harmonic(s)"), in which case the parameter's value will be displayed in its 'Native' display mode, followed by the symbol (e.g. "12 Harmonic(s)" for an Int-typed parameter or "12.54 Harmonic(s)" for a Float-typed parameter). For additional control over the numerical component displayed, a sprintf-style string may be used (e.g. "%0.2f Bogon(s)", which would display a value such as ".87 Bogons").
Exponent
When set to a value other than 1., the parameter's input and output values will be exponentially scaled according to the factor entered in this column.
Steps
The number of steps available between the minimum and maximum values of a parameter. For instance, if the parameter has a range from 0.-64., with Steps set to 4, the user can only set the parameter to 0, 21.33, 42.66 and 64.
Parameter Visibility
For automatable parameters (Int, Float, Enum), 'Stored Only' disables automation, although parameter values are stored in presets. 'Hidden' causes the parameter's value to be ignored when storing and recalling data. Non-automatable parameters (Blob) are 'Stored Only' by default, and can be set to 'Hidden', if desired.
Update Limit (ms)
Speed limits values triggered by automation.
Defer Automation Output
Defers values triggered by automation.
