Aftertouch on Slider Bottom does not work

[Peter Ostry]

• MIDI Mapping
     Btm. slider ctrl. "AT"
• Slider
     Btm. edge "Ctrl."

Does not work, AT is not sent.

In the Slider Btm. edge submenu we can select CC and Pitchbend, they work. I guess AT is filtered out?

I also tried "Nothing" in the Slider Btm. edge submenu just to see if AT goes through because it is already set in the Mapping menu. But no, nothing is nothing.
