Hit Controller
Hit Controllers filters timbre, speed, or velocity messages and sends those messages to modules within. Let's say you have two samplers and you want soft hits to trigger one sampler, and hard hits to trigger the other sampler. Simply drag both of those samplers into a Hit Controller set to velocity and arrange them so that the low velocity sampler is in the first step, and the high velocity is in the second step. That's what hit controller is for.
