I originally tried to put most of the modules to the top row that have a screen and knobs on top, and patch points on the bottom, to make tweaking easier. Pam is top middle, because it's often my most patched module, and I was thinking that it needs to be as close as possible to everything else.
Thanks a lot for taking the time for this. I copied it over to my designs, I'm going to go over the changes you made.
