alt Hacker NewsCreating Rhythms by Hollos and Hollos. I am not much of a fan of it but my expectations were high, the person who recommended it to me made it out to be exactly what I was looking for and it was not at all what I was looking for. It primarily focuses on things of Euclidean Rhythms ilk, simple to execute but can be quite effective. Despite not being what I was after I think I got my $10 worth.
I too bought this book and was somewhat disappointed. Some of the algorithms seems too contrived and specific. (All the code is here: https://abrazol.com/books/rhythm1/software.html)
I guess my wish would be a companion to Geometry of Musical Rhythm with lots implementations of code to demonstrate concepts. Euclidean Rhythm implementations seem to be everywhere, but there is SO MUCH MORE to cover.
Still, I'm kind of stuck on this idea that there may be a way to map the discrete mathematics of this rhythm stuff into a continuous mathematics for more natural and fluid rhythmic expression. It's just a theory and a few experiments so far.
