Euclidean Rhythms are a relatively new discovery, but really it's just some basic math that captures a lot of common (and uncommon) rhythms and meters. You don't need a special module to play with them, you just have to know what they are and that's what this video is for.
There's even a whole 'zoo' of rhythms at the end that you can plug into a trigger sequencer and get started with. If you're not interested in the history, context, and math stuff, you can jump straight to the Euclidean Basics chapter.
[Note: Around the 10 minute point there is an inconsistency between what I am saying and what the music is doing. Unfortunately, there's nothing I can do about it now, but it is a known issue]
