Any experience with Pro Tools panners?

Hi all,

I am wondering if anyone has any experience with programming panners in Pro Tools. For example, when a mono track is bussed to a 5.1 track, a 5.1 panner is added to the mono track so you can move the single around discreet channels.

I’ve had a lot of trouble locating anything about programmatic panning in the AAX SDK (no surprise). I know there is hardware that does this so it must be possible.

Any AAX plug-in programmers with pointers on where to look for some info on this? Cheers!
