Vortex Sound Research

I'm wondering if there's a module that basically acts as an automated A/B switch for CV.

Example: I want to take 2 tempos from Pam, 1 quarter beat and 1 eighth beat, to the same kick to alertnate rhythms. Obviously a mult is involved, but is there some kind of switcher that I could run the quarter note CV into A, the eighth note CV into B, and some sort of CV signal as a master control to switch between A and B rhythms.
