active [int] (default: 1)

Toggles the object's active mode. When active is set to 0, mouse action does not cause output and the inactive colors are used.

activebgcolor [4 floats]

When the active attribute is set to 1, this attribute sets the background color displayed when the button is off in RGBA format.

activebgoncolor [4 floats]

When the active attribute is set to 1, this attribute sets the background color displayed when the button is on in RGBA format.

annotation_name [symbol] (default: )

The string that is prepended to annotations. This shows up in the Info pane in Live, and the clue window in Max.

bgcolor [4 floats]

When the active attribute is set to 0, this attribute sets the background color displayed when the button is off in RGBA format.

bgoncolor [4 floats]

When the active attribute is set to 0, this attribute sets the background color displayed when the button is on in RGBA format.

blinktime [int] (default: 100)

When parameter_mappable is enabled, the object will be available for mapping to keyboard or MIDI input using the Mappings feature.

transition [int] (default: 0)

The parameter automation of live.button stores 0 and 1 values. The transition attribute specifies when a bang message will be sent to the outlet.
0 Zero->One: output a bang when the parameter value changes from 0. to 1.
1 One->Zero: output a bang when the parameter value changes from 1. to 0.
2 Both: output a bang when the parameter value changes from 0. to 1. and when it changes from 1. to 0.

Possible values:

0 = 'Zero->One' ( Output a bang on 0. to 1. transitions )
Outputs a bang when the parameter value changes from 0. to 1.

1 = 'One->Zero' ( Output a bang on 1. to 0. transitions )
Outputs a bang when the parameter value changes from 1. to 0.

2 = 'Both' ( Output a bang on 0. to 1. and 1. to 0. transitions )
Outputs a bang when the parameter value changes from 0. to 1. and when it changes from 1. to 0.

size [2 floats]

varname [symbol]

Sets the patcher's scripting name, which can be used to address the object by name in pattr, scripting messages to thispatcher, and the js object.

Parameter Attributes

Order

Typeint

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

Typeint

Parameter Mode Enable (not available from Parameters window)

Link to Scripting Name

Typeint

When checked, the Scripting Name is linked to the Long Name attribute.

Long Name

Typesymbol

The long name of the parameter. This name must be unique per patcher hierarchy.

Short Name

Typesymbol

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

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 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

Typelist

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

Typeint

Sets the Modulation Mode used by the Live application. The modulation modes are:

None
Unipolar
Bipolar
Additive
Absolute

Modulation Range

Typelist

This parameter is only used with the Absolute modulation mode. It specifies defines the range of values used.

Initial Enable

Typeint

When checked (set to 1), the UI object can store an initialization value. The value is set using the Initial attribute (see below).

Initial

Typelist

Sets the initial value to be stored and used when the Initial Enable attribute is checked.

Unit Style

Typeint

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

Typesymbol

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

Typefloat

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

Typeint

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

Typeint

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)

Typeint

Speed limits values triggered by automation.

Defer Automation Output

Typeint

Defers values triggered by automation.

Messages

bang

Performs the same function as anything.

int

Arguments

input [int]
Performs the same function as anything.

float

Arguments

input [float]
Performs the same function as anything.

anything

Arguments

input [list]
When any message is received in the inlet, the button flashes briefly and a bang is sent out the outlet.

assign

Arguments

assign-input [float]
The word assign, followed by a floating point value, causes that value to be stored and displayed and sent out the live.button object's outlet. 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.

(mouse)

Clicking on the live.button object will cause it to flash briefly and send a bang message out the outlet.

Output

bang

A mouse click or any message in the inlet causes the live.button object to flash and send a bang message.
