the way spark is set up....There isn't much of a way to control this other than riding the volume. I have factory kits, expansion kits, user kits from the internet, my own kit designs, etc.... The volume is all over the place. The controller DOES have a master volume, and I often turn this way down after switching kits. I start very low and just ease my way in! Sorry I don't have a better solution. Spark is a pretty diverse sound engine and samples can really be anything so... Factory kits have number authors as well, some really red line it with multiple compressors and limiters, and some have very natural sounds. Spark also has a lot of vintage drum machine emulations, which are going to sound way less hot than a newer dubstep or hip hop kit. You could always slap a limiter on your master channel every time, or route it into your daw with a comp/limiter on the channel to make this easier if you wish. I agree the kits that start with clipped samples should not be happening....
