I don't know if this is what you guys are talking about but on the Force, the Pad FX can use the screen & or 64 pads. The pads are velocity & pressure sensitive so can use them like a vol fader. You can even reverse them so that the vol turns up when you press on it. They can be set to act as off/on triggers as well. You have to set the pad to Pad FX mode so the they don't trigger the drum/sample on the pad which is call note mode on the Force:
