XO Expansion: Beneath Waves by Robot Koch.

Beneath Waves brings the cinematic sound world of Robot Koch into XO as 115 beat presets and 163 one-shot samples. Robot Koch is the alias of producer and composer Robert Koch, who blends field recordings with sounds processed through custom-built tape machines, then often layers ten or more into one until their sources are hard to name. He invites imperfection in rather than cleaning it away, so tape warble and noise stay part of the sound. It requires XO, sold separately.
