EuclideanRhythm

Implementation of the algorithm described in http://cgm.cs.mcgill.ca/~godfried/publications/banff.pdf

Synopsis

    use EuclideanRhythm;

    my $r = EuclideanRhythm.new(slots => 16, fills => 7);

    for $r.list {
        # do something if the value is True
    }

Description

This provides an implementation of the algorithm described in http://cgm.cs.mcgill.ca/~godfried/publications/banff.pdf which is in turn derived from a Euclidean algorithm. Simply put it provides a simple method to distribute a certain number of "fills" (hits, beats, notes or whatever you want to call them,) as evenly as possibly among a number of "slots". The linked paper describes how, using this method, you can approximate any number of common rhythmic patterns (as well as not so common ones.)

You could of course use it for something other than generating musical rhythms: any requirement where a number of events need to be distributed over a fixed number of slots may find this useful.

Installation

Assuming you have a working installation of Rakudo then you should be able to install this with zef:

zef install EuclideanRhythm

or if you have a local copy of this repository:

zef install .

in the directory you found this file.

Support

This is a fairly simple module such that the scope for any egregious bugs is quite limited, however if you have any suggestions, patches or comment the feel free to leave a post at https://github.com/jonathanstowe/EuclideanRhythm/issues.

Because it is quite simple in both scope and implementation I would anticipate that any higher level functionality (such as providing timing,) would be implemented in another module.
