Precision Specifies the number of decimal places for the value display. The default
value is 3 and the maximum number is 6. This setting has no influence on the
actual output of the Object. You have to scale the output using expressions or
on the Target side.
Color Drag the colour bar to change the colour of the Knob.
Behavior Properties
Cursor Mode If set to Limited, the Knob will respond to a new cursor only if the original
one has been destroyed (i.e. finger is raised)
Get Newer means that whenever a new cursor appears inside the
Object’s area, it gains full control of the Object
In Barycentric mode each cursor, old and new, has the same amount of
influence on the Object
Control In Polar mode, the Knob respond to the polar position of cursors, relative
to its center point.
In Linear mode, the Knob responds to cursor drag on the vertical axis
Physics Can be one of three settings: None, Interpolate, or Mass-Spring.
If Physics is set to None, the Knob jumps instantly to the value dictated by
the cursors’ positions.
If Physics is set to Interpolate, the Knob rotates toward new values
according to the value of Attraction. Larger values for attraction (up to 1)
cause the Knob to reach a new value more quickly. As the Attraction value is
lowered, the Knob takes longer to arrive at the finger position. When
Attraction is set to 0, the Knob cannot be moved by your finger.
If Physics is set to Mass-Spring, Attraction and Friction are both active.
Attraction works as described above under Interpolation. Friction ranges
between 0 and 1. Lower values of friction mean that the Knob will tend to
keep moving. With a value of 0, the Knob will essentially never stop moving.
Values of 1 for Attraction and Friction are essentially the same as if Physics
is set to Interpolate.
Attraction See the discussion of Interpolation and Mass-Spring modes under Physics
above.
Friction See the discussion of Mass-Spring mode under Physics
above.
OSC Data
Lemur->Host The x variable is transmitted from the Lemur followed by one value
representing the Knob’s position.
/ObjectName.x <value>
Host->Lemur The x, Attraction and Friction and value Variables can be received by the
Lemur. Please note that, if you have an expression working in the value field,
the Lemur will always use the value of the expression and not the data
received via OSC.
/ObjectName.x <value>
/ObjectName.attraction <value>
