I'd like to have some more insight on that topic. What are the opinions of Axe users with regards to auto-synchronizing footcontroller and Axe-FX?
I have read several comments stating that this kind of synchronization is a must-have, showstopper if it's not available. Then I've seen several comments stating that in practice this isn't interesting because it's too slow. Here I read that it's not necessary since changes can easily be done on the footcontroller.
I'm about to look into this kind of functionality, that's why I'd like to know up front how useful this synchronization between both actually is, and what the real life arguments are against what I believe is the most interesting approach, namely what Javajunkie specifies here : let the footcontroller be in control of effect activation, then you are always in sync, even without needing 2-way communication.
