I hope it's ok to mention this here! I've made a windows/mac app that creates up to 16 Sample Live Drum Rack Kits from user folders of samples. It also randomizes Volume, Pan and Release times with definable min/max ranges per pad. It has the ability to save Presets, has Colour Themes and it also creates MPC Programs for the modern generation of MPCs and software.
It's still a beta, but is available for an early bird price of $19.99 as a result. There are a few more features to come such as the ability target existing files and some basic conversion between MPC and Live presets. I'm expecting to be at v1.0 within the next 2 weeks.
It's a great way to generate interesting Kits from all the samples you own.
