Sampling is supposed to be fun
Prior to shortcircuit it wasn't as fun as it could be.

Shortcircuit was created as a reaction against the ongoing trend where software samplers are being designed with the primary intent of library playback. It is intended for people who, like us, consider a sampler to be a musical instrument in its own right, and not just a way to emulate other instruments. It has been a very high priority to make sure that adding and editing individual samples is as fast and logical as possible. 

The sample hierarchy in shortcircuit allow you to place samples directly at the highest level of the multi, without having to deal with instrument hierarchies and patches. Want to add a sample to your song? Just drag & drop the sample into shortcircuit and you're ready to go. Samples can be put in groups for multi-sampling and kit-building, but the complexity is only there when you need it.
