Ladik S-090 Dual Probability Skipper

Two-channel gate skipper with voltage-controllable probability

4 HP Eurorack module

The S-090 Dual Probability Skipper is a two-channel gate filter that randomly passes or blocks incoming gate and trigger signals based on a user-set probability. It brings controlled chaos and organic variation to rhythmic patterns, allowing sequences to breathe and evolve without full repetition. Its exclusive mode and two randomization algorithms give it a range of musical characters from lightly humanized grooves to generative polyrhythmic textures.

Features

  • Two independent probability skipper channels
  • Ch2 gate input normalled from Ch1 for easy single-source dual-probability operation
  • Probability knobs double as CV attenuators when CV is patched
  • 0V or below maps to 0% probability, 5V or above maps to 100% probability
  • Internal jumper for Exclusive Mode — only one channel output fires per pulse
  • Ch1 has priority in Exclusive Mode with normalled input
  • Two selectable randomization algorithms via internal jumper
  • Cluster Algorithm supports true 0% and 100% probability extremes
  • LEDs on each gate input and gate output for visual monitoring
  • Powered from positive 12V rail only

Controls & Jacks (16)

  • Channel 2 Probability— Sets probability (0-100%) that input pulses pass to output on channel 2. Also acts as attenuator for CV input.
  • Channel 1 Probability CV— CV input for modulating channel 1 probability (0-5V range)
  • Channel 1— LED indicator for channel 1 activity
  • I
  • Channel 1 Gate In— Gate/trigger input for channel 1
  • Channel 1 Gate Out— Gate output for channel 1, passes pulses based on probability setting
  • Channel 2 Gate In— Gate/trigger input for channel 2 (normalled from channel 1 if not connected)
  • Channel 2 Probability CV— CV input for modulating channel 2 probability (0-5V range)
  • G
  • Channel 1 Probability— Sets probability (0-100%) that input pulses pass to output on channel 1. Also acts as attenuator for CV input.
  • IN
  • Channel 2 Gate Out— Gate output for channel 2, passes pulses based on probability setting
  • Exclusive Mode Jumper— Internal jumper: when set, outputs block each other so only one channel can pass a pulse at a time; ch1 has priority
  • Algorithm Select Jumper— Internal jumper: when set selects a different randomizing algorithm that creates more regular random but prevents true 0% and 100% probabili
  • Channel 1 Gate In LED— LED indicator for channel 1 activity
  • Channel 2 Gate In LED— LED indicator for channel 2 activity
