Now connect an LFO to one of the two clock inputs (bottom left or bottom right jack) and you should see the centre LED light up when a signal is received. Make sure the middle switch is in the centre position, and the left switch is in the up position. Getting StartedĬonnect the left sequence output (second jack from the bottom left) to an envelope gate input controlling a sound source, or something like the trigger input of a drum module. We have based our implementation on the work of Toussaint, Bjorklund and Euclid. Then, in 2005, a Professor of Computer Science called Godfried Toussaint linked up the dots and presented in a research paper the connection between the work of Euclid, Bjorklund, and musical rhythms. He also published his work with a proof of the efficiency of his method. A scientist named Bjorklund applied it to nuclear physics, in order to optimise the operation of the SNS particle accelerator. Of course, Euclid’s work can be applied to more than just rhythmic patterns. From Brazilian Samba and Bossa-Nova, to Bulgarian folk dances, thirteenth century Persian drum patterns, and complex poly-rhythms of West and Central Africa.

The cultural and historical range covered by these rhythms is nothing short of breathtaking. Across the globe, from ancient to modern times the rhythms that pervade human existence can be generated using the same, simple algorithm. As it turns out, his method is the same as what people have used to divide beats into rhythms. In the third century BCE, the Greek mathematician Euclid described a way to determine the largest common denominator of any two integers. The name (Στοιχεῖα, Stoicheia, or Elements) comes from the title of Euclid’s book Elements in which the algorithm was first described. It algorithmically generates rhythmic sequences from an input trigger signal.
