XO identifies and collects one-shot samples stored anywhere on your computer or hard drives and sorts them by similarity. It brings your samples of choice into a new creative context that facilitates experimentation.
You can use XO as stand-alone or with your favorite DAW along with other plugins. You load XO as an instrument into your DAW. XO is used preferably but not exclusively for beat making and rhythm production using, what you consider to be drum sounds.
