Products in Big Fish Audio's KLI Series (Kontakt Loop Interface) include a custom interface for tweaking loops and sounds beyond what was previously possible. Each loop is given its own patch and can be extensively edited by manipulating the various slices of the loop. In addition, groups of loops that play together have been given their own patch, making it easy to quickly arrange and mix sounds on the fly.

Even though you can manipulate these sounds using Kontakt and your MIDI controller,  it is importnat to note that KLI is loop-based, not a virtual instrument.
