Hi
About mis-aligment, there is a “calibration mode” available.
I just checked that once - but because my gear is fine, nothing to adjust.
No big deal
Just press and hold Bank L, Bank R and Nudge R while power on the unit.
All the rest is to follow the advises on the screen 
It’s from a knowledge article on the avid artist-us homepage.
BTW: I used once the CC121 for some time - changed to the Euphonics - will never change anymore 
Cheers
