Move a slider to output values


Resembles a sliding potentiometer, outputting numbers restricted to a specified range, offset by a specified number, and multiplied by a specified number.


Produce output by dragging onscreen... or display numbers passing through




bgcolor [4 floats]

Sets the slider background color in RGBA format.

elementcolor [4 floats]7.0.0

Off Color

floatoutput [atom_long] (default: 0)

Toggles floating-point output from the slider object. The default is 0 (off).

knobcolor [4 floats]

Sets the slider knob color in RGBA format. The knobcolor attribute is mapped to the color style color.

knobshape [int] (default: 0)7.0.0

Knob Shape

Possible values:

0 = 'Indicator+'
1 = 'Less Rounded'
2 = 'Rounded'
3 = 'Triangle'
4 = 'Rectangle'
5 = 'Indicator'

min [float] (default: 0.)

Sets value that will be added to the slider object's value before it is sent out the outlet.

mult [float] (default: 1.)


orientation [int] (default: 0)

Sets the slider object to a horizontal or vertical data display.
Automatic : (the default) sets the display dependent on the size of the slider - longest side of the rectangle that describes the slider sets the orientation.

Possible values:

0 = 'Automatic'
1 = 'Horizontal'
2 = 'Vertical'

parameter_enable [int]

Enables use of this object with Max for Live Parameters and allows for setting initial parameter values in the Max environment.

relative [int] (default: 0)

Sets the way that the slider object responds to mouse clicks. In relative mode (the default) the slider keeps its relative position when you click - Moving the mouse outputs higher or lower values in relation to that relative position. In absolute mode, the slider will automatically jump directly to the clicked location.

Possible values:

0 = 'Absolute'
1 = 'Relative'

size [float] (default: 128.)

Value range

style [symbol]7.0.0

Sets the style to be applied to the object. Styles can be set using the Format palette.

thickness [float] (default: 100.)7.0.0


Common Box Attributes

annotation [symbol]

Sets the text that will be displayed in the Clue window when the user moves the mouse over the object.

background [int] (default: 0)

Adds or removes the object from the patcher's background layer. background 1 adds the object to the background layer, background 0 removes it. Objects in the background layer are shown behind all objects in the default foreground layer.

color [4 floats]

Sets the color for the object box outline.

fontface [int]

Sets the type style used by the object. The options are:

bold italic

Possible values:

0 = 'regular'
1 = 'bold'

Possible values:


hidden [int] (default: 0)

Toggles whether an object is hidden when the patcher is locked.

hint [symbol]

Sets the text that will be displayed in as a pop-up hint when the user moves the mouse over the object in a locked patcher.

ignoreclick [int] (default: 0)

Toggles whether an object ignores mouse clicks in a locked patcher.

patching_rect [4 floats] (default: 0. 0. 100. 0.)

Sets the position and size of the object in the patcher window.

position [2 floats]


Sets the object's x and y position in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its size unchanged.

presentation [int] (default: 0)

Sets whether an object belongs to the patcher's presentation.

presentation_rect [4 floats] (default: 0. 0. 0. 0.)

Sets the x and y position and width and height of the object in the patcher's presentation, leaving its patching position unchanged.

rect [4 floats]


Sets the x and y position and width and height of the object in both patching and presentation modes (if the object belongs to its patcher's presentation).

size [2 floats]


Sets the object's width and height in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its position unchanged.

textcolor [float]

Sets the color for the object's text in RGBA format.

textjustification [int]

Text Justification

Possible values:

0 = 'left'
1 = 'center'
2 = 'right'

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



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.



Specifies the data type. The data types used in Max for Live are:

Enum (enumerated list)

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.



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:


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).



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").



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.



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.



Sends out the number currently stored in the slider.



input [int]
The number received in the inlet is displayed graphically by slider, and is passed out the outlet. Optionally, slider can multiply the number by some amount and add an offset to it, before sending it out the outlet.



input [float]
Converted to int .


Clicking and dragging with the mouse causes will change the position of the slider and send a number value out the object's outlet.



input [list]
The word set , followed by a number, resets the value displayed by the slider, without triggering output.



values [list]
The word setminmax , followed by two numbers, sets the low and high range values for the slider object. The floatoutput attribute will automatically be set.



Numbers received in the inlet, or produced by dragging on slider with the mouse, are first multiplied by the multiplier, then have the offset added to them, then are sent out the outlet.

Although the numbers that can be output by dragging are limited by the range of the slider, numbers received in the inlet are not limited before they are sent out the outlet.
