Setting the channel option is allready working. I use it very offten and like it. It is available in the effectpage.Setting the AMP or CAB channels directly from the pedalboard can be a cool option, e.g: for fast comparison while you are tweaking.
I don't know why the information to grab the AMP/CAB names is not shared at the Axe-FX III, as it was at the II. We could open a request at the Wish List
Maby making it available in the scenepage is more obvious.. then the looperpage has to make room for it.
Adding it to the wishlist is a good option. Will do that asap. Still have some hope a contributer will come along and share his/her knowledge
About the channel switching. You think amp1/cab1 abcd switching shouls also be combined with 1 button push? Ive seen many reguest, but since it can be done, would it be of any use?
