Your second message clarified matters considerably. I think.

If I understand you correctly, OSC would be the transport for controller
data like pan/gain, etc, which would then be stored in ardour as normal
automation data.

I am in the process of improving ardour's OSC support - and rolling a
protocol specification to output pan/gain/etc via OSC...

see http://tracker.ardour.org/view.php?id=2239 for current progress and

... and am very interested in the types of messages potential
controllers generate, and use cases in general. What kind of device(s)
are you using?

As for storing OSC data directly on a timeline track, and regenerating
it on playback, this strikes me as doable (in ardour 3.x!), and
"interesting" for driving external OSC devices that ardour does not need
to understand (say, for example, theater lighting). On the other hand
a jack transport sensitive jack client to generate OSC external to
ardour would be simpler, and perhaps already exists.
