About Euclidean AUv3 Sequencer
Euclidean Sequencer is an alternative incarnation of the classic step sequencer that has become very popular in the modular realm. It is based on Euclidean rhythms developed by computer scientist Godfried Toussaint in 2004. Euclidean rhythms have their roots in Greek mathematician Euclid’s algorithm, which involves using the greatest common divisor of two numbers to place hits in a sequence as evenly as possible across a set timing divisions.
In practice this is actually simpler than you might think, and Euclidean Sequencer is a great way to auto generate complex musical sequences with no prior knowledge of how it actually works.
Euclidean Sequencer is an AUv3 plugin that can be loaded inside any popular host application that has flexible MIDI routing.
You can define up to 4 Euclidean rhythm parts, each part is referred to as a band. The bands are labelled A-D and colour coded RED, ORANGE, GREEN and CYAN. Together these 4 bands create a pattern, and you can create up to 16 seperate patterns per song patch.
Since each band can specify its own note sequence and output MIDI channel, you can create some quite sophisticated rythms patterns, driving 4 seperate instruments at once. Even better you can seamlessly switch patterns to create even longer evolving sequences. Patterns follow a specified key, scale, or defined chord.
You can even use MIDI input to automatically make note sequences conform to the currently playing chords.
Please note: This is an AUv3 plugin instended to be used inside your favourite host DAW such as AUM, Cubasis, Loopy Pro etc. It will work with any app that has flexible MIDI routing.

Recognises more chords in Chord Recognition mode. See help for newly added the chord chart.
Fixed a MIDI recording issue when Song Mode is enabled.
You can now toggle Events On/Off in Euclidean mode (not just PolyRhythm and PolyMeter).
Long press on Band Enable buttons to access the new Auto Rotate options toolbar.
Added an 'Inv' (Invert) button to each of the 4 bands.
Long press 'Inv' (Invert) causes bands in Euclidean mode to reconfigure with steps == events.
Added a coloured chevron on the Band Enable buttons to signify an Auto Rotate is active.
*The new Auto Rotate options allow you to automatically rotate a band after a given number of rotations. There will be a new video tutorial specific to these new versions very soon.
**This version of Euclidean contains a theoretical paper on Euclidean, PolyMeter and PolyRhythms written by David Collett. I recommend this to anyone wanting to learn the differences between the varoius modes and confident this will help users get the most out of Euclidean. Thanks to David for his amazing work on this paper.
