Hi
Of course you could program the new features as you need them, which may be easier than re-doing all you old custom ones.
That’s what I meant 
I already mentioned during the work with the new CB7 mixer, that various commands are not present now in the MC control, and some commands are even no more programmed in CB7 
But I still think, that to add some new functions into the known set-up is more easy then to figure out all commands from scratch.
To be honest, the basic set-up, which came with the CB 6.5 EUCON adapter was more or less useless.
Cheers
