If you want to find the default CC mappings for each of the Stompboxes, you can see them in H9 Control under Pedal  ->  MIDI Settings  ->  Assign MIDI CC to pedal functions.  There are also default XMIT CC settings, but I don’t think those are available in H9 Control.  I could be wrong here, but you may have to go System menu diving for those in the pedal itself.

But there’s nothing magic about those default CC numbers.  It looks like Eventide selected blocks of CC messages that wouldn’t conflict from Stompbox to Stompbox.  As Spacejam said, customize your own system for CC messages.  With the [CC] Learn feature, you’d don’t even need to know exactly what you’re sending to the Stompbox.
