03In depth

Sound Character and Sampling Approach

Robot Koch builds the sounds in this pack from field recordings processed through custom-built tape machines. The tape stage adds warmth, warble and movement to the material.

According to the developer, Koch often layers 10 or more sounds into a single final texture, so the origin of each element is hard to identify. The result is organic, textural and deliberately imperfect, with recognizable qualities of water, wind, rain and tape noise blended together.

The pack focuses on cinematic rhythmic textures and tape-infused beats rather than conventional drum kits.

Using the Presets and One-Shots in XO

Because the pack requires XO, its presets are loaded and edited inside that instrument. The 115 presets give you finished multi-layer patches, and the 163 one-shot samples provide raw material for building your own sound.

The developer positions the pack as a source of inspiration for new tracks, with XO's editing tools available for building variations of each sound.
