Yes, I have cleared internal prgs and set up already several times,with the 2 method described in the manual .

Take an Eventide H8000fw.

Set in Disp B an effect,by exemple ,"Galaxy borders2" ,or Polyring pre or whatever .

Set in Disp A a reverb, like Majestic Plate  by exemple or Black hole.

In Disp B , assign the global parameters "Levels" in the remote control page to "volume".  (with the select and hold method) .  Now , with the midi pedal, you'll see  and hear that the Wet/Dry mix of galaxy borders will go from 0 to 100% . In the "levels" page  of the effect,  all the  8 out channels are underlined.

Don't make any other remote assignments.

Tell me  if you see now in the parameters of  one of the 4 soft key of " galaxy borders" if a  specific parameter does vary from his min to his max levels when you hit the pedal.   It does !

Go  now in disp A  with processor A/B key , hit the vol pedal and see what happens in the parameter and levels pages of Majestic plate or Black hole .. you'll be surprised .

so easy !
