It seems the /ping command for OSC only has effect if the "API/feedback" is toggled on in the OSC device manager.
It would be useful if one could /ping even when API/feedback is toggled OFF. For instance, when a control device is first connected, it could /ping to get all the current settings (or at least the ones it cares about.)
"API/Feedback" is good for debugging, but it is a lot of continuously streamed data... most of which isn't needed most of the time. /ping would allow us to determine when to refresh ALL the data.
