4ms catalyst sequencer price : $395.00

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.

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 re-install with the controller artwork visible.

specifications:
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
