Despite the awesomeness and scope of Kontakt, I still find myself craving something into which I can quickly drag and auto keymap audio clips. Something like the free version of Structure which comes with Pro Tools. That thing is awesome for beat chopping. You just take your drum loop, chop it into eight pieces, drag them into Structure, and it automatically maps them to consecutive notes on the keyboard. I haven't found anything comparable in a free VST version, although to be fair I haven't really looked hard.
