Euclidean Circles

3/6 channel 16 step Euclidean rhythm generator with an unique pattern visualization in 3U, 10hp Eurorack format. Outputs 1-3 are the “on-beat” triggers and 4-6 are the “off-beat” trigger signals, all 5V. Triggers 4-6 can also be used as a second set of 3 channels so 6 independent rhythm channels are available in total.

  1. Really great work!

    I’m wondering if you have ever considered adding the functionality of being able to rotate the rhythm in time. Example: Let’s say I have hits on 1, 4, 7, 11, 13 (that is, the 3-2 clave). I’d like to be able to rotate that rhythm to be on 2, 5, 8, 12, 14. Or all the way around to 3, 5, 9, 12, 15 (2-3 clave).

    1. yes, that’s possible. you can set the length, fill and rotation (starting point) of each Euclidean rhythm individually

    1. Erthenvar jacks are 1mm higher than Thonkiconns. With Thonkiconns, the encoder pins stick out just enough that they can be soldered easily, with Erthenvar jacks they would not reach through the PCB. Only v1.5 of the PCB had a footprint for Erthenvars, all later revisions only take Thonkiconn (Or Kobiconn) jacks.
