Euclidean Rhythms is an algorithmic rhythm player for Reason. It means that instead of coming up with and playing your rhythm patterns yourself, a rhythm pattern is generated for you according to Euclid’s ancient algorithm. By tweaking just a few knobs in real-time, or using automation or CV, you can get almost endless variations and inspiration for your tracks!

Euclidean also offers plenty of precise manual control if you want it. For instance you can mute individual steps or draw their velocities. With Slide and Shuffle you can fine-tune the groove.

Get inspired by Euclidean Rhythms!
