Output numbers by moving a slider onscreen


slider is a user interface that resembles a sliding potentiometer. It outputs numbers restricted within a specified range, offset by a specified number, and multiplied by a specified number.




bang Sends out the number currently stored in the slider.
int 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.
float input [float]
Converted to int.
(mouse) Clicking and dragging with the mouse causes will change the position of the slider and send a number value out the object's outlet.
set set-input [list]
The word set, followed by a number, resets the value displayed by the slider, without triggering output.
setminmax low-and-high-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.


Name Type g/s Description
bgcolor float Sets the slider background color in RGBA format.
bordercolor float Sets the slider border color in RGBA format.
floatoutput int
Toggles floating-point output from the slider object. The default is 0 (off).
knobcolor float Sets the slider knob color in RGBA format.
min float
Sets value that will be added to the slider object's value before it is sent out the outlet.
mult float
Specifies a multiplier value. The slider object's value will be multiplied by this number before it is sent out the outlet. The multiplication happens before the addition. The default value is 1.
orientation int
Sets the slider object to a horizontal or vertical data display.
0 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.
1 Horizontal
2 Vertical
relative int
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.
size float
Sets the number of steps (range) of the slider object. The default value is 128. Setting the size to 1 disables the slider visually (since it can only display one value). Any specified size less than 1 will be set to 2.


brgba list (3 ints) brgba is a legacy RGB alias for the bgcolor RGBA attribute. See here for more information.
frgba list (3 ints) frgba is a legacy RGB alias for the knobcolor RGBA attribute. See here for more information.

Menu Items

Name Description
Color Choosing the Color... menu item from the Object menu when the object is selected opens a color picker, permitting adjustment to the appearance of the slider object.


int: 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.
