I'm having a a bit of trouble connecting Ardour to OSC so I can use TouchOCS on the ipad.

I have got this far....
On ipad, TouchOSC conects with pd and I can see the values being passed as I move the slider/toggle a button.

But I can't seem to see how to get ardour to use this information.
I have set 'Use OSC' in the options, and edited my ardour2rc with the line : <Option name="osc-port" value="YourChoiceHere"/>

Thats about all I've got up to now. I've tried googling, found bit's but nothing that answers my question.

Thank for your time,
