8-bit digital pipeline for delay, loop, and chaos

8 HP Eurorack module

Rostock is a digital FIFO shift register and data pipeline for the Leibniz Binary Subsystem, operating on 8-bit parallel data to create delays, loops, and binary pattern generators. Its length is variable from 1 to 64 stages with optional looping and XOR scrambling, making it a versatile tool for rhythm sequencing, audio-rate glitch effects, CV delay, and chaotic pattern generation.

Features

  • 8-bit parallel digital shift register / FIFO data pipeline
  • Variable length 1 to 64 stages, voltage controllable via bipolar -10V to +10V CV
  • Looping function captures and repeats any data sequence
  • XOR scramble mode for cyclic binary pattern generation
  • Eight individual clock inputs for per-bit timing control
  • Outgoing clock input to substitute output data clock for downstream modules
  • 8-LED bank displays real-time status of each bit output
  • 2-digit LED display for length and CV attenuation depth
  • Clear button and gate jack to reset pipeline memory instantly
  • Remote gate control for loop and scramble functions
  • Operates at up to 2MHz clock rate enabling video-rate applications
  • Leibniz Binary Subsystem component — connects via 10-pin ribbon data cables
