Euclidean AUv3 Sequencer is a unique version of the classic step sequencer that many people love in the modular music production community. The app is inspired by Euclidean rhythms, which were developed by computer scientist Godfried Toussaint in 2004. These rhythms come from a method described by the Greek mathematician Euclid. This method uses the greatest common divisor of two numbers to evenly distribute hits across a series of timing divisions.

In practice, using the Euclidean AUv3 Sequencer is easier than it seems. This app helps you automatically create complex musical sequences without needing to understand the details behind it.

As an AUv3 plugin, the Euclidean AUv3 Sequencer works in popular host applications that support flexible MIDI routing. You can define up to 4 Euclidean rhythm parts, known as bands. These bands are labeled A, B, C, and D, and they are color-coded RED, ORANGE, GREEN, and CYAN. By combining these 4 bands, you can form a pattern and create up to 16 separate patterns for each song patch.

Each band allows you to specify its own note sequences and output MIDI channel. This flexibility means you can create sophisticated rhythm patterns, driving multiple instruments all at once. Additionally, you can switch between patterns seamlessly, allowing for longer and more evolving sequences. The patterns can follow a specific key, scale, or chord.

The app even has MIDI input recognition, which helps ensure that the note sequences match the chords currently being played.

It's important to note that the Euclidean AUv3 Sequencer is designed to be used in your favorite DAW, such as AUM, Cubasis, or Loopy Pro. It will work well with any application that supports flexible MIDI routing. However, it is not compatible with GarageBand, as that platform does not support MIDI plugins.

In terms of features, the Euclidean AUv3 Sequencer offers a 4 Band Sequencer and allows up to 16 Patterns per patch. Each band can handle up to 64 events. You can enjoy seamless pattern transitions and have control over the output port and channel. There are also global speed settings and the ability to use a Randomize function with varying complexity.

The app supports note probability and offers modes like reverse and PingPong for creative expression. There’s even a Latch mode, a 4 Band velocity mixer, and controller support for added flexibility. Additionally, it includes Gate Mode and is fully AUv3 compatible.

Overall, the Euclidean AUv3 Sequencer stands out as a powerful musical sequencing tool, ready to enhance your musical projects with its innovative features.
