Avid Technology PRO TOOLS MIX 51 - Manual (Page 15)

Panner with all controls in “write” automation enabled mode
Thus, to migrate the Left-Right panning automation of Mix 51, you must copy it
into the Front Position and Rear Position pan automation tracks of the Pro Tools
panner. To do so, select the track automation for the Mix 51 Left-Right pan
control and copy it. On the track you wish to copy this automation to (a track
routed to a 5.1 output for instance), select the Front Position pan automation for
that track and using “Paste Special” “To Current Automation Type” you can paste
the Mix 51 L-R automation into the track. Then select the Rear Position pan
automation for that track and use “Paste Special” “To Current Automation Type”
again.
Similarly, copy the Front-Rear control using the same technique to finish copying
the X-Y panner movement into a Pro Tools HD surround track. You can then use
the same method to copy divergence controls, center percent, LFE, and volume
control.
