standalone analog labs running a DX7 Arturia plug in the aftertouch works fine.
Running the DX7 as a plugin still didn't work. Then I did more research and the issue is pro tools default (2019.5) is to filter out mono and poly aftertouch messages, ergo the reason nothing seemed to work in PT. Setup > Midi > Input Filter.
I also found that earlier versions of Midi Control Center had that bug of 0 thru 2 as a min max range, and in fact, it was by default min=2 max=0 which confused me. Here is what I found that works with Analog Lab 3. Go to the midi control center (latest version downloaded today, and today is August 10, 2019) and click the Device tab top right. Then try the following: Key aftertouch min of around 80 and max at around 127. Then pick a aftertouch curve. I find EXPonential forces the least amount of pressure and provides maximum effect earlier than LINear, but Linear is smoother at getting into the range from noticeable to max effect. LOGorithmic seems to require more force than EXP to get there and then shoots to max faster so I don't really like this one.
