I would get rid of the Varigate 4+ and keep the Mimetic Digitalis sequencer and add a good sequential switch or matrix mixer. That would give you lots of pattern generation and variety. I added a sequential switch recently to my setup and it adds spice. If I had more space, I'd add a matrix mixer. Let's you mix CV and route various ways. Boss Bow Two is a cool switch with tricks that play well with Pam. Erica Synths also makes a neat sequential switch.
