So, I'm working on some things where I'm adding most of the instruments, working alone ans sending the client in Nashville rough mixes. I can't for the life of me set up an auto punch in/out. I watched a few different YouTube videos and they are all PT9, and seemingly something has changed in PT10. I highlight the section I want the punch to happen, and I see the red arrows at the top, but not the yellow to define pre and post roll. I have enabled pre/post roll in the dropdown. If I try to click outside of the highlighted section, the highlight disappears.
Not the answer you're looking for, but I gave up on auto-punch a long time ago. I just cut + paste + mute the area I want to replace, duplicate the track (un-checking the top box), back 'er up and hit red. Very lowbrow, but fast & easy.
There is a dropdown menu on the top right hand of the transport which allows you to see the pre post roll times. However, the easiest way to enable pre post roll is to option click with the selector before and after your selection to your desired pre/post times. Command K will also turn pre and post roll on and off. Of course, you can also manually type in pre post roll times on the transport if you choose to view that section of it.
