MIDI A-P are internal connections which simultaneously carry front panel controller knob 
data and MIDI continuous controller data. 
The 16 controller knobs on the PX-7 front panel work just like MIDI real-
time controllers. The controller knobs are permanently assigned to 
controllers A-P. The front panel knob (A-P) and incoming MIDI controller 
messages assigned to that letter, both control the same parameter that you 
select in the PatchCord screen.
