Has anyone found an efficient way of creating cadences other than very short chord chains or dedicating one arpeggiator to the task?

There are now (v7/8) so many ways to modulate on ARP that I made this crib sheet to remind myself. It is probably not comprehensive so I'd love to capture some more suggestions.

Having the option to save the set of Mute and Follow states per patch rather than as global would be very useful. I can find o suggestion that this is possible in the manual or have I missed something?

I have two Midicake ARPs which I want to control a Roland MC707's eight channels. Each ARP sends midi to a midi merge box and into the MC707. What would be the best way to sync the set up?
