4ms Introduces Catalyst Sequencer and Catalyst Controller Eurorack Modules

Details on each follow:

Catalyst Sequencer

The Catalyst Sequencer combines a traditional clocked step-sequencer with an unconventional phase-based sequencer to produce a new paradigm in sequencing. Eight precision CV sequencer channels can be simultaneously driven by a clock, a phase 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.

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 Controller is a macro controller with eight precision CV outputs and a responsive crossfader to morph between scenes. A scene is a snapshot of up to eight CV outputs, like a modular preset. Traverse a “pathway” composed of multiple scenes using the crossfader or an external CV signal, or immediately jump using the scene buttons. Record CV and slider movements, and play recordings back via a button or external trigger.

Each output has sub-millivolt precision and a maximum range of -5V to +10V. Channels have an adjustable morphing curve, can be quantized to common scales, restricted to a particular voltage range, or set to output gates.

Whether used as a CV preset manager, seamless transition generator, chord sequencer,

CV recorder, or experimental CV playground, the Catalyst Controller puts control of your

modular at your fingertips.

Based on the original Catalyst module from Emblematic Systems.

Two modules in one!

The Catalyst Sequencer can turn into a Catalyst Controller, and vice-versa! Hold down a special button combination to change between sequencer and macro controller modes. If you end up buying one module but liking the other one more, you can remove the double-sided faceplate, flip it over, and re-install with the other artwork visible.
