Parameter Attributes
Orderint
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 Enableint
Parameter Mode Enable (not available from Parameters window)
Link to Scripting Nameint
When checked, the Scripting Name is linked to the Long Name attribute.
Long Namesymbol
The long name of the parameter. This name must be unique per patcher hierarchy.
Short Namesymbol
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.
Typeint
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 256
values, with a default range of 0-255 (similar to the char data type used
in Jitter). When working with Live UI objects whose integer values will
exceed this range, the Type attribute should be set to Float,
and the Unit Style attribute should be set to Int.
Range/Enumlist
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).
Clip Modulation Modeint
Sets the Clip Modulation Mode used by the Live application. The modulation
modes are:
None
Unipolar
Bipolar
Additive
Absolute
Clip Modulation Rangelist
This parameter is only used with the Absolute modulation mode. It specifies defines the range of values used.
Initial Enableint
When checked (set to 1), the UI object can store an initialization value. The value is set using the Initial attribute (see below).
Initiallist
Sets the initial value to be stored and used when the Initial Enable attribute is checked.
Unit Styleint
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 Unitssymbol
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").
Exponentfloat
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.
Stepsint
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 Visibilityint
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)int
Speed limits values triggered by automation.
Defer Automation Outputint
Defers values triggered by automation.
Messages
bang
Sends the current value out the outlet.
int
The number received in the inlet sets the level (in dB).
- db-input
[int]
float
The number received in the inlet sets the level (in dB).
- db-input
[float]
assign
The word assign , followed by a floating point value, causes that value to be displayed and sent out the mc.live.gain~ object's outlet. The value, however, will not be stored. If the Parameter Visibility attribute is set to Stored Only, the assign message will not add the new value to the Live application’s undo chain.
- assign-input
[float]
init
Restore and output the initial value.
(mouse)
Click and drag the slider to change the amplification. Hold down the Shift key for more precise mouse control.
outputvalue
Sends the current value out the outlet.
rawfloat
A raw normalized value (between 0. and 1.) received in the inlet is converted to a real value, stored, displayed by mc.live.gain~ object, and the current value is sent out the outlet.
- input
[float]
set
Sets the current value without causing output.
- set-slider-value
[float]
signal
In left inlet: The input signal (left channel) to be scaled.
In right inlet: The input signal (right channel) to be scaled.
Output
float
Out second outlet: The current slider value in dB, when dragging on the slider with the mouse or when mc.live.gain~ receives an int or float.
Out third outlet: When an output is triggered, a raw normalized value (between 0. and 1.) is sent out this outlet.
