I also whant to point out that if you whant to change something small in the IO in above rows, then your ***** up.
Lets Say you put in the first line an outboard stereo compressor. You create a stereo in. You go further and add in the second row a Stereo Synthesizer. You do your thing and add your lets say 32 Channels of stuff in there.
Suddenly you have the great idea that you also whant to have a left/right thing of your compressor from the first row. There is no way back.
You have to go to the bottom of the I/O and create there a left/right setup for your compressor that is on the top. And why? Because you can not move annything inside the I/O once it is in there.
So if i whanted to have this clean now, i would have to start all over again, delete my 32 channels of gear, and start all over again.
Please make the I/O flexible
