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. This app is not compatible with GarageBand as it doesn't support MIDI plugins. Features 4 Band Sequencer 16 Patterns per patch. Up to 64 events per band. Seamless pattern transitions. Output Port and Channel control. Per Band and Global speeds. Randomize function with varying complexity. Supports note Probability. Reverse and PingPong modes. MIDI Chord recognition. Latch mode. 4 Band Velocity Mixer Controller support. Gate Mode.

Perhaps with a chaos control. Currently, the randomiser must always be triggered manually to generate MIDI data once. Perhaps something will be added in the future. That would be great and would definitely enhance Euclidean. ### 1/5 — Not working in GarageBand *2024-12-28* App is not found as AUV3 in Garage Band. Isn’t loading as IAA as well.. So its completely useless for me. Unable to reach developer. Downloaded 4 other apps of his, they are fine, this one seems to glitchy. **Developer response:** Sadly, GarageBand doesn't support MIDI only AUv3's. I'm not sure why but I'm sure Apple have their reasons. You have to step up to Logic to be able to load these, but the app is compatible with most other DAWs. ### 4/5 — Really fun *2024-10-15* Edit: I figured it out. It wasn't hard. Adding a fifth star - I love it! Unfortunately, I can't find any instructions on how to integrate this with Logic Pro. The company's web site is offline and there's no help included with the app. YouTube hasn't been helpful either, showing only tutorials based on AUM. I don't use AUM (nothing against it, I own a copy, but it's not one of my regular tools). Please help! ### 4/5 — Really fun *2024-10-08* Unfortunately, I can't find any instructions on how to integrate this with Logic Pro.

Please help! ### 5/5 — Thanks for updating for logic support *2024-01-25* I have it working in the logic daw, however it first fell to be recording MIDI notes to the logic session. How is this accomplished? ### 5/5 — Need to control both events and steps *2023-12-14* Wonderful app, and I was very pleased when the dev said they would look at exposing *both* the events and steps to midi control. (I’m still not sure why these weren’t the first two things to become mappable.) as it is it’s great, but by not allowing control of both main parameters it kind of has one arm tied behind its back, so to speak. ### 5/5 — Great, just needs a small amount more controllability *2023-06-18* I think this app is great, adds some great easy options for throwing a melody in quick, and really repays fiddling about with the music theory bit. I have 2 feature requests/questions though.1- Why can’t notes be tied across steps if the piano grid is there to hold that info? 2- Why can’t I assign a cc to the number of fts (like I can easily do with number of events)? There may be a logical reason why these are silly ideas but especially #2 would enhance jammability on this app greatly. ### 5/5 — Amazing *2023-02-15* Really impressed how good this app is. NB there is also a really thorough set of tutorials made by the dev (PaulTheMusicMan), also useful for deciding whether to purchase. ### 5/5 — Wenn man die Funktionsweise versteht - genial *2023-01-27* Der Entwickler (meines Wissens Einzelperson) ist für mich meist ein wenig rustikal. Ist aber einfach mein Gefühl beim Bedienen der GUI, denn ich bevorzuge übersichtlich/minimal. Aber trotz dieser Geschmacksdifferenz muss ich Euclidean 5 Sterne geben! Einfach genial mit den unterschiedlichen Möglichkeiten, die eröffnet werden - z.b. Akkorde/chords über die Pianorolle im unteren („versteckten“) Teil der App. Hier liegt denke ich auch die Crux bei der letzten schlechten Bewertung. Auch ich rannte in mein „Verderben“ und änderte die Tonhöhe einer Lane/eines Channels, es kam trotzdem kein Mucks aus dem Drumcomputer - das liegt daran, dass wenn im oberen Teil von Euclidean die Tonhöhe auf die richtige Note gesetzt wird, schreibt es in der Pianoroll Ereignisse. Die Pianoroll-Ereignisse/Noten werden bevorzugt verwendet und wenn z.b. ein drumcomputer angesteuert werden soll müssen diese pianoroll-Ereignisse gelöscht werden! Danach funktioniert der neu gesetzte Notenwert! Bitte beachten, dass es natürlich pro Channel unterschiedliche Pianorolls gibt. Viel Spaß ### 5/5 — Love this sequencer *2023-01-26* One of the best inspirational sequencer out there, especially if your into Berlin School electronic or any kind of electronic music. Not the simplest to work out but also not that difficult. Well worth putting the effort in. Another brilliant app from a long line of great apps from this dev ## Frequently asked questions about Euclidean AUv3 Sequencer ### What is Euclidean AUv3 Sequencer?
