4ms Catalyst Sequencer Eurorack Module (20 HP)

4ms Sequencer Overview

Generate patterns and sequences with the 4ms Catalyst Sequencer, a Eurorack module that combines a traditional clocked step-sequencer with an unconventional phase-based sequencer to create a new paradigm in sequencing. The Catalyst Sequencer features 8 precision CV sequencer channels that can be driven by a clock, a phased CV, or scrubbed manually with the crossfader.

Each of the eight channels has its own sequence length, quantizer, transposition, clock divider, randomization, voltage range (max -5V to +10V), and selectable CV (precise 16-bit resolution) or Gate mode. The Catalyst Sequencer module ships with a ribbon power cable and mounting screws.

Details

• Sequences range from 1 to 64 steps
• Eight output channels, each can be CV or Gate
• Step forward, backwards, ping-pong, or randomly
• Smooth, responsive crossfader can Scrub the sequence
• Phase CV input scrubs the sequence with an external CV:
  • Ramp-up plays the sequence forward
  • Triangle wave plays ping-pong
  • Complex waveforms create complex patterns
• Each channel can have a different Start and Length, and can Reset to any step
• CV outputs can be set to -5V to +10V maximum, or limited to +/-5V, +5V, +3V, or +1V
• CV outputs can be unquantized (sub-1mV resolution), or Quantized to common scales
• Gate outputs fire one or more triggers when activated
• Transpose globally or per channel
• Randomization of channel values/gates, with per-channel Random amount
• Glide (glissando) or gate Ratchet can be set per step
• Tap Tempo button
• Copy/paste a page (eight steps) or an entire channel

Phase-Based Sequencing

Phase-based sequencing is an advanced form of sequencing where each step is selected by CV. The Catalyst Sequencer has a smooth, responsive crossfader that scrubs the sequence, playing it forward or backwards to track your motions. Patching in a CV signal will do the same: a ramp-up CV plays the sequence forwards, a ramp-down plays it backwards, a triangle plays it ping-pong, and complex waveforms generate new interesting rhythmic and melodic patterns.

Catalyst Controller

The Catalyst Sequencer can also turn into a Catalyst Controller. Hold down a special button combination to change between sequencer and macro controller modes. If you end up liking the Controller more, you can even remove the double-sided faceplate, flip it over, and reinstall with the Controller artwork visible.
