I find that after doing some heavy automation changes in a project I need to move some of my regions around. Often the automation applied to Bus and Aux channels does not move accordingly with the automation data on the tracks. Here is a quick tip on how to successfully move the automation data on your Bus and Aux channels as well.
I have created an Ultrabeat Multi-channel Instrument. I have sent the kick out to an auxiliary channel. Below is my arrangement before I move the regions:
You’ll see that when you open the automation lane and select all (Command-A) it looks as though you've selected all the respective regions. But when you try to move the regions— including the automation data — you will notice the automation data on Aux channels does not move.
Here is the arrangement after I have moved all the selected regions. You will see the Bus/Aux channel data has not moved.
This can get quite confusing when you have been working on a mix and have applied numerous automation data to your Aux and Bus channels. Then when you decide to move selected regions around in the track, the automation on those channels gets left behind.
I have found the best solution is to draw a region on the area of the relevant Aux or Bus channel with the Pencil Tool (Esc-2) where you wish to move or place automation data.
Here is the arrangement with my included region on the Bus/Aux channel:
