VIRAM Octopus Sequencer Sneak Preview

Dr Viktor Ratza of VIRAM shared this sneak preview of his upcoming Octopus Euclidean pattern sequencer, a 3U hardware step sequencer.

The VIRAM Octopus is based on the idea of Euclidean Rhythms, which are described by Godfried Toussaint in his 2005 paper, The Euclidean Algorithm Generates Traditional Musical Rhythms.

Euclidean Rhythms distribute beats over a series of steps as equally as possible. For example, distributing 4 beats over 16 steps equally gives you the standard “four on the floor” rhythm. Euclidean Rhythms tend to make sense musically because of the physics of playing percussion instruments.

The Octopus offers features to help make these algorithmically-generated beats more interesting, by allowing you to use a differing number of beats in each of its 8 modules, rotating patterns, customizing and randomizing velocities and timings, and more.

In addition to beats, the Octopus lets you create melodic progressions by triggering chord notes. Several modes are available to let you add variations, manipulate melodies and interact with the Octopus sequencer in real time.

Ratza plans to launch the Octopus later in 2022. See the VIRAM site for details.

    1. Yeah, I keep thinking why was it built this way, looks like separate units. Interested to see how this developes and how its used.

    2. Hi .. this is Viktor 🙂 The single modules (the “arms” of the Octopus Sequencer) won’t work alone. They need to be connected to some master module (the “head” of the Octopus). I wanted to keep the Octopus Sequencer as modular as possible, so you can also mount it in your Eurorack system, as it also offers CV and gate output to work with your modular systems.
