xod/common-hardware/pot has 2 input and 2 output ports. If this is the one you are using and it has no ports, you probably have modified the original and you will no longer get updates. If this is the case, your workspace will have a xod folder under
__lib__ in your workspace. My workspace is in c:\Users<username>\xod. You can find yours by selecting File > Switch Workspace in XOD. If any folders that start with “xod” exist under
__lib__, you should exit XOD, delete or rename any xod folders, then restart XOD. This will restore the original built-in nodes.
