 ## Rhythm generators
 	
 We included a bunch of popular rhythm generators in Topos such as the euclidian rhythms algorithms or the one to generate rhythms based on a binary sequence. They all work using _iterators_ that you will gradually learn to use for iterating over lists. Note that they are levaraging <ic>mod(...n:number[])</ic> that you just learned about!
