OK Instruments SPILL

Six-effect stereo powerhouse with generative modulation and sequencing

20 HP Eurorack module

SPILL is a stereo multi-effect Eurorack module built on the Daisy Seed platform, offering six buffer-based effects including stutter, granular, slicer, filter, delay, and reverb. It features an internal mod matrix, LFO, ADSR, envelope follower, CV recorder, randomizer, per-effect sequencer, logic gates, and channel assignment, making it a dense performance and generative effects hub. Its musical character ranges from subtle coloration to chaotic texture generation, capable of functioning as two independent mono effect chains.

Features

  • 6 buffer-based effects: Stutter, Grains, Slicer, Filter, Delay, Reverb
  • Stereo processing with per-effect channel assignment (Left, Right, Stereo)
  • Can operate as 2 independent mono effect chains
  • Built on Daisy Seed microcontroller platform
  • 3 modulation buses per effect
  • Modulation sources: CV 1-4, Envelope Follower, Sine LFO, ADSR, CV Recorder, Random
  • Per-effect randomizer with adjustable threshold and parameter exclusions
  • Logic section with OR, XOR, AND, NAND, NOT, 2nd, 3rd, 4th trigger logic per effect
  • Per-effect sequencer with clock divider, direction control, and record/randomize
  • Internal ADSR envelope with selectable trigger source
  • Envelope follower converts audio to modulation curve
  • CV Recorder records up to ~40 seconds of CV or audio as looping modulation
