Touching the display and dragging upwards or downwards changes the value.
Double tapping the display resets to a pre-defined reset value (r).
Comes in three variations: GenericMidi display, Pan display and Percentage Display.

How to map: look inside the containers for the "hidden" object (Knob) - map x expression to your desired midi - OSC target
How to set the reset value: look inside the "hidden" object - change "r" expression to the desired value....note: r is in range 0 to 1 so for example for the Pan resetting to "Center" r=0.5
