Koma Elektronik Komplex Sequencer

The Koma Elektronik Komplex Sequencer is unequivocally the most complex sequencer in all of Eurorack. Skeptical? Consider this: the Complex is comprised of four 16-step sequencers, each featuring their own patch points, control knobs, and switches. The sequencers can be used separately or in tandem for the generation of complex patterns. Even better, the Komplex emits both CV and MIDI, meaning it can also control any synthesizer with a MIDI input.

Each of the unit’s sequencers features dedicated start/stop buttons, directional switches governing five different modes, a clock division knob with dedicated CV input, and a transposition input for influencing key changes and tonal shifts.

The Komplex contains all these great features and more, with an intuitive and accessible front panel interface that does not require any menu diving whatsoever.

KOMA ELEKTRONIK Komplex Sequencer: Basic Overview
The KOMA ELEKTRONIK Komplex Sequencer controls the 1 V/Oct input of the Harvestman Hertz Donut via Sequencer A’s CV output. Sequencer A’s Gate Output controls the Cutoff CV of the KOMA ELEKTRONIK SVF-201 Filter and the 4ms VCA Matrix, which the Hertz Donut goes through. After creating the basic patch, we use the other sequencers to modulate play mode, transpose and gate length.

The KOMPLEX SEQUENCER is a musical monster built around four full-featured 16-step sequencers that allow and invite the user to use one or more of the sequencers to sequence the other one. The KOMPLEX SEQUENCER has no screen or submenus; all features have their own dedicated controls, and all features have their own dedicated in- and outputs on the large 86-point patch bay. Each sequencer has its own start and stop buttons, a quantizer (switchable between chromatic, major & minor scales), one-shot-mode and five different play modes (forward, backward, ping-pong, ping-pong reversed, random).

By patching both internal and external CV-sources to the patch bay of the KOMPLEX, the user is able to control the parameters for Sequence Start Point, Sequencer Clock Division, the amount of the Glide between the steps, Skip Step, Repeat Step and Repeat Length. Also, you can Transpose the whole sequence via CV, start it with an external trigger signal and use, for example, an LFO or another sequence to control Sequence Length or Gate Length. This adds up to 20 in- and outputs per individual sequencer, which, when you include the CV recorder outputs, adds up to 86 CV patch points on the whole machine, all conveniently located on the front panel.
