I'm actually going to suggest TWO modules, both 4 hp in width.

The first one is the Ladik S-186, and the other is Tesseract's VC Logics. The first one is useful to shift gate/trigs rhythmically and then move them off of the beat. And then with the second one, you can take both processed and UNprocessed clock signals and run them through a Boolean gate, which then outputs gates based on the given logic states at each Boolean. The VC Logics also allows you to switch Boolean logic per gate by CV, which can be fun as it has the ability to really alter the build's behavior.
