the apc40 has all of the knobs on the right side that let your control your sends/returns/panning, and your effects racks, as well as your global controls, and a crossfader(which is rarely used by anybody, but fun to dick around with occasionally). you could also look at putting in a bit of effort and building a monome using an arduino chipset and some pads, and building your own case, and your end result will be similar to a launchpad for half the price.
