I use my ksp to manage clock. I sync with midi connected to my computer. I don’t really need a clock divider, but you should be able to sync your clock divider with it. Additionally, the ksp and bsp both have the ability to run sequences at different rates and time division.
You can have the step pros be the global clock, and just output the cvs to your modular, or do like me where you send midi to sync and send note, velo and mod messages that get translated to cvs by the ksp.
I can literally have my modular play a midi file from my computer in this way.
But like I said, even without a computer, you can just use the step pros to control everything. The clock divider would only come in if you wanted another subdivision from the same track for instance.
