Name: Castle Process
draft: false
short-description: Fort Processor-inspired harsh noise processor with chopped
  external audio and a bass pulse voice
summary: Castle Process is a performance card built around chopped external
  audio, crude internal squarewave energy, aggressive switching between sources,
  and a separate bass pulse layer. It is designed as a playable
  sound-destruction tool rather than a clean effect or faithful clone.
