Fun fact: Knife Party use the Digital Audio Workstation (DAW) application Nuendo for their production. In an interview with Sound on Sound Swire mentions he was using Logic for a long time, but eventually switched to Nuendo, mainly due to the linking system and workflow environment which let him work faster. Most of the sounds emulated are virtual instruments (VST).
