The 4ms Catalyst is a serious sequencer for experimental electronic music producers. Its blend of deterministic and probabilistic sequencing, coupled with the phase scrub, makes it a powerful tool for generating unique and evolving textures – a real workhorse for anyone diving deep into generative sound design.

Product Description

  • 4ms Catalyst Sequencer
  • Eurorack Module
  • 8-Channel step sequencer
  • Each channel can output either control voltage (range: -5V to +10V) or gate signals
  • The steps (scenes) can be played sequentially via clock signal or selected directly via phase scrub slider or phase CV
  • Adjustable per channel: length (1-64 steps)
  • start
  • playback direction
  • phase
  • transposition
  • clock divider and random/probability
  • Quantiser with 14 selectable scales per channel
  • Adjustable pulse width and swing per step in gate mode
  • 8 Memory locations for sequences
  • 8 CV or Gate outputs
  • Clock and reset inputs
  • Tap tempo button
  • Power requirement: 60 mA (+12 V) / 25 mA (-12 V)
  • Width: 20 U
  • Depth: 24 mm
PROS
  • • Exceptional random/probability engine yields complex, evolving patterns.
  • • Phase scrub slider offers incredibly intuitive and tactile sequence manipulation.
  • • Quantizer provides precise tuning across a wide range of musical scales.
  • • 8 memory locations allow for quick recall of intricate sequences.
CONS
  • • The learning curve is steep; mastering all parameters takes dedication.
  • • Limited modulation options beyond the phase control and CV inputs.
  • • Physical depth (24mm) can be restrictive in shallow Eurorack cases.

Frequently Asked Questions

Unlike simple rewind, the phase scrub allows real-time, granular manipulation of the sequence playback position, effectively creating live edits and rhythmic variations.
It's far from a gimmick; the nuanced probability controls allow for subtle variations or chaotic bursts, adding organic feel and unpredictable elements to sequences.
While capable, it's best suited for those already familiar with sequencing concepts; the sheer number of parameters can be overwhelming for beginners.
