To Set Symmetry (Ramp)
Symmetry is defined as the percentage that the rising period of the ramp takes up in
the whole period (as shown in the figure below). This parameter is only available

The setting range of symmetry is from 0% to 100%. The default is 50%.
Tap the Symm parameter input field to input the desired symmetry value with the

You can also use the arrow keys and the knob to set the parameter value: press
down the knob to enter the editing mode, use the arrow keys to move the cursor to
select the digit to be edited, and then rotate the knob to modify the value. Besides,
you can use the knob to switch between different parameters.
