Nils Liberg maintains a fantastic resource of Kontakt scripts, a tutorial and even a free/donationware programmer-oriented script editor that comes in Windows and OS X flavors.

Nils is behind the script that powers the Scarbee Black Bass instrument, and his scripts are mainly geared towards creating realistic instrument emulations. If that’s not your cup of tea, a few of the scripts look ripe for experimentation, like the MIDI filter and the FX morph.

These were written for Kontakt 2 - I haven’t tested them all but the MIDI filter and FX morph load up fine in K3. I think they’d be great starting points for taking things even further… hmmm, I wonder if I could hack the FX morph to use four instead of two presets and fade between them with a 2D control surface…
