Hi, sorry for posting a DIY project here, but I thought people might enjoy it. It's a Euclidean Polyrhythm Sequencer

I'll let Ruin & Wesen explain Euclidean Rhythms: "Last week, I stumbled upon the amazing paper by Godfried Toussaint called The Euclidean Algorithm Generates Traditional Musical Rhythms, which shows how the euclidean algorithm used for example for timing systems in neutron accelerators can generate most of the traditional european and african rhythms. It is about distributing a set amount of pulses (which Godfried calls n) over a discrete amount of timing intervals (called k)."

If you're interested, there's a nice flash app that lets you play with Euclidean Rhythms here.

My module takes incoming clock and outputs 3 channels of pulses, with two encoders to set n & k for each channel. In the demo, the bottom channel is driving a sequencer, and the top two channels are driving kick/snare percussive sounds directly.

It's built around an arduino. Happy to answer any questions!

Awesome stuff! Will you be posting some more details about the build/software? I'd love to make one myself.

Euclidean Rythm!

Super Nice ! do you have your project documented somewhere ?

Was looking into that a while back .. after a couple of awesome articles:

This one !

this one pretty good

Adding CV over the pot controls would bring it to a whole new level. Are the patterns generated predetermined? Could they be changed via updating?

Really cool!

That groove sounds organic and funky as all get out. Would definitely be interested in learning more...is the brains behind the whole thing an app you wrote for the ardiuno? Not sure if "app" is even the right word, but anyway I mean "something you could post that we could use without needing to know how to program"?

I had this concept for an algorithmic beat generator module that involved three channels of the same Euclidian algorithm for generating polyrhythms.
I have also tested this on arduino and it works great.

My implementation lets you set large numbers using the segemted display so that something like 100 slots with 7 beats spread over them would be possible.
The slip control allows you to slip the sequence forward or backwards relative to the other sequences.

I really like on your implementation the use of the led matrix display, makes it fun to watch!
