A rotary encoder is an adjustable rotary control that manipulates a device parameter and displays values of a device parameter.<\/p>\n

When a Custom Panel is activated, the rotary control (inner ring) changes the linked parameter values as the end user clicks and slides it around it to the desired value position (like twisting a nob). The rotary encoder is controlled by right-clicking with the mouse and moving to the top or right to increase the value and moving to the bottom or left to decrease the value.<\/p>\n

The LED meter (outer ring) reflects the selected parameter values, which are usually the same as those linked to and adjusted by the rotary control.<\/p>\n

Controls can be managed in the Custom Panel designer and, once the Custom Panel is activated, utilized by the end user. This control must be linked to a parameter to function properly.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
