Demo: A Geometric Approach to Generate Musical Rhythmic Patterns in Haskell
summary
A small Haskell DSL called RTG DSL in Haskell generates and manipulates rhythms by representing patterns as binary lists for onset/rest and exposing a RhythmicPattern type class that aims to lift pattern types into algebraic groups (Erlangen program idea) so group operations and inverses can compose rhythms. Examples include Euclidean/“ukian” distributions and a second time-based rational-list pattern; sound is emitted via OSC to TidalCycles+SuperCollider, which works but currently produces unsynchronized players because buffering/scheduling is not yet implemented.
