The Sensory Percussion sampler allows you to cycle through samples based on how you play the drums. To use Sensory Percussion’s controllers to cycle through samples, first click on a pad with a sampler that has a sample-stack. In the sampler, above the sample-stack, check the box labeled control. Now create a controller and drag and drop it onto the number box next to the the control checkbox. That assignment now controls the the order in which the sample-stack cycles.
It’s good to remember that - because the samples are cycling, and the stack isn’t sounding all at once - you can normalize all of the samples in the stack or mix them all to the same level without worrying about clipping.
