This is set up in the same way as CC controls. Simply right-click the control you wish to automate and select “Add LFO Automation.” This will let you add one of the 4 available LFO options to the control.
You can sync the LFO to your host tempo using the sync option in the bottom left, and change the LFO parameters on the left-hand side of the window. Use the green check mark to apply your settings. You can edit the LFO settings by right-clicking on the control again or find the settings in the Matrix on the right side of the interface.
