Welcome, Spencer!
To use the rotaries, you would want to select the “Relative” checkbox in the action, then set the value to “-1” for a left turn of the rotary, and “+1” for the right turn of the rotary. (If you wanted the step to be higher or lower, you can change the 1 to another number - I go into an advanced method of changing these numbers by selecting a “course” and “fine” adjustment in the 2nd video)
I would highly recommend having a look at my videos that I created which show some of the basics of creating layouts using the RCP module. The process is the same for any of the mixers that the RCP module supports - TF/CL/QL/DM.
