I'm not sure how to switch CC7 to CC4, but I can always midi learn the pedal to parameters I want to control.
 
I haven't yet tried Velocity or Keyboard or Keyboard Gate. I'm not sure what you mean by "Alternate for every other note that you play".
 
By way of thanks, B Rock, I recorded a jam.

I just found this useful book in Safari Books online and I thought I'd mention it. My work gives me a free subscription. It never occurred to me to look for Cakewalk stuff.

And I just found X3 Power on Safari books!!
