The Knob Node displays a customizable knob on the Patcher, and outputs a constant value controlled by it. It’s very useful for building custom Nodes with turnable knobs, or controlling multiple Nodes from a single place.
Inputs
The Knob Node itself does not expose any inputs. However, when placed inside a subpatch, the Knob Node creates an input on the subpatch container Node itself. That input can then be used to control its value from the outside, similarly to how many Nodes have controllable settings, such as the Gain Node’s Gain setting.
Settings
Value
The output value. Clamped between Min. value and Max. value.
Min. value
Minimum value of the control knob.
Max. value
Maximum value of the control knob.
Origin
The starting point of the knob’s visual fill. This setting is visual, and has no effect on the output.
Curve
Adjusts how the knob scales as you turn it. A value of 1 represents a linear value. A value greater than 1 causes values to change slowly at the start, and then speed up towards the end (useful for frequency-related settings). This setting is visual, and has no effect on the output.
Step
Rounding step. For example, if set to 1, the Value will be an integer.
Marks
Adds dashes into the knob’s visual fill. To use multiple values, separate numbers with a comma, e.g. “1, 1.5, 2” (without the surrounding quotes). This setting is visual, and has no effect on the output.
Order
Sets the Knob Node’s appearance order when used in a subpatch (e.g. a Subpatch Node). Affects both input order, and the Knob Node’s appearance order on the properties panel. Lower values appear first. Has no effect when used outside a subpatch.
Theme
Sets the knob’s color. This setting is visual, and has no effect on the output.
Dividers
Adds dividers when the Knob Node appears on the properties panel of a subpatch (e.g. Subpatch Node). This setting is visual, and has no effect on the output.
Size
Sets the knob’s size. This setting is visual, and has no effect on the output.
Outputs
Control Output
The value specified by the Value setting. This value is always constant, and thus enables constant folding in connected Nodes if they support it (unless the Knob Node is controlled through a subpatch input using a non-constant connection).
