K2579 Step Sequencer

Description

Programmable Digital Sequencer

The K2579 is a compact and powerful programmable two-part modular sequencer and performance instrument. It supports simultaneous input, output and control via analog and MIDI connections and nearly all programming and performance parameters can be modified in real-time. More than just a simple step sequencer, the K2579 allows sequences to be built, arranged, modified and controlled seamlessly. The entire unit is programmed through a simple interface consisting of an LCD, two knobs and seven buttons. Eight front-panel jacks allow patching the CV/GATE output pairs, inputting clock and reset signals, and inputting two continuous voltages which can be mapped onto various performance parameters for real-time control from other modules.

Up to 16 sequences of 16 steps each (per part) can be loaded at once. Sequences can be chained together, looped or completely controlled manually. The unit features a built-in clock for convenience, but can also sync to an external analog clock pulse or MIDI clock. Using the MIDI functionality requires a K1600 MIDI Converter or other breakout device for interfacing the MIDI signals.

The K2579 Step Sequencer brings new potential to the world of modular synthesis by offering new ways of making music. Building on the success of the K4815 Pattern Generator, the K2579 is a step sideways. Where the K4815 excels in fast creation of rhythms and melodies based on intelligently designed ingredients, the K2579 offers user control over every note and function, and also offers twonote polyphony by supporting two parts per sequence.
