Komplex Sequencer

Powerful step sequencer built around four well-equipped full-featured 16-step sequencers communicating via both MIDI and CV/Gate. There are no screens or submenus.

All features have their own dedicated controls and have their own dedicated in- and outputs on the large 87-point patch bay. Every aspect of this sequencer is CV-able. Lastly a seven bank CV Recorder is on board and can output up to 5 banks at once!

The Komplex Sequencer opens up a whole new world of creative possibilities and starts where other sequencers have stopped!


Availability: In stock

Our step sequencer lets you construct complex musical patterns, both via MIDI and CV/Gate. Built around four full-featured 16-step sequencers in a compact and light enclosure, the Komplex Sequencer is a powerful tool both live and in the studio.

The Komplex Sequencer stays true to KOMA’s philosophy to interact with your gear like you would with an instrument; all features have their own dedicated controls, inputs and outputs on a large 87-point front-panel patch bay inviting you to instantly engage with the machine.

By patching both internal and external CV sources through the patch bay of the Komplex, you can control any parameter of the sequencer immediately and “sequence the sequence.” Controls include Speed, Sequence Length, Gate Length, Play Mode, Glide, Division, Transpose, Repeat, Sequence Start Point and Skip. Additionally, the sequencer can vary output range and also has a quantizer on board operable in different scales.

And not only is the sequencer compatible with almost any synthesizer with CV/Gate, MIDI note, velocity and CC information can also transmitted by any of the four sequencers. Lastly a seven bank CV Recorder is on board and can output up to 5 banks at once! The Komplex Sequencer opens up a whole new world of creative possibilities and starts where other sequencers have stopped.

Finally the Komplex is in production again. Current waiting time from order to shipment is 6 – 8 weeks and availability is very limited.
