I love modular sequencers! Having a good trigger sequencer to pair up with the Vector is quite useful. Maybe something like an Eloquencer or WMD Metron would be fun for you to expand. I like clocks as well and Pamela New Workout is fantastic in this area.

Having separate trigger/clock sequencers and separate CV/pitch sequencers allows sequencing to be deconstructed into its elements. I use a Temps Utile running either a Euclidean, step, or logic functions to drive a Memitic Digitalus from Noise Engineering. There are trigger inputs on the MD that control step advance, reset, or even skipping around +-4 steps, or randomly.

This decoupling allows for more complexity from two simpler sequencers.
