I haven't quite made it all the way through this thread yet, but I'm going to go ahead and mention a request --- if it's already been made, just count this as a bump:
I don't disvalue the performance macros/ scenes, but they (as they are currently implemented) don't exactly foster 'happy accidents' as everything must be premeditated/ intentionally programmed, etc.
If it were at all possible to generate random macro/ scene assignments, I think that would go a long way to subsiding the flood of users calling for Control All to be implemented.
Or perhaps provide us with either a preference in settings or a button + pad combo that would override any existing assignments to make way for pre-programmed macro/ scene routings for manipulating certain params throughout devices. (The obvious continued downside is that the macros are only unipolar so you can't have one macro controlling master pitch up and down, etc) idk. hmm.
