I am having this issue as well – the only CC that appears to have been saved at some point was the “BYP” CC# but none of the others will save so I have to set them up each time I power the H9 back up before each gig.  Also, although the BYP one saved at some point, I’ve since switched to using the “ACT” control instead with my GCPro but as with everything else, it comes back up with the previous saved CC# and will not allow me to save the change.

Is there any resolution please?

Thank you!
