This might seem esoteric, but it's a huge oversight for post work:
When I import tracks from a session that does NOT start at hour 1 (let's say from Reel 2/hour 2) into a session that DOES start at hour 1... The new tracks are placed at the correct spot in the timeline, with all associated mix automation data EXCEPT the send automation! Any send automation is separated from the regions and placed out of sync at the beginning of the session.
Avid, please fix this. The more we mix in the box, the more important the handling of mix automation is.
