I use a Behringer FCB1010 to send the CC’s (and ultimately the PC changes once the H9000R can handle them).

I do  not use an expression pedal to cycle through the CC’s since I can send the exact CC# from my pedal board.

Am I supposed to send CC=15 for tweak #2 as per your table? 

Lastly, how can I permanently override the settings of a given tweak # so I have my own 10 tweaks?
