I thought I have done this in the past but can't seem to get it going now. I want to input 24 audio tracks and have the in/out ports cascade to meet my X32 in/out ports.
 
I go to add multiple, but it only lets me set one port for master out and one send.
 
How can I cascade the ins and outs to match my 32 channel interface?? Surely I am missing something.

ok, I had to select all inserted tracks and then do the input as a series. That worked. It would be nice to have that implemented in the add audio tracks multiple dialog.

Another nice item would be to expand the full input options to show all inputs like the output selection does so you don't have to do additional clicking.
