Archaeopteryx: Lambdas in Detail
summary
Archaeopteryx is a Ruby library that generates MIDI by mapping MIDI note numbers to arrays of floats — a probability matrix of gates between 0.0 and 1.0 — and uses lambdas as first‑class strategy objects invoked later. It runs on gems midi lib and mediator, represents drum patterns as float matrices (kick = 36, clap = 37), re‑evaluates definition files every few measures, and demos working live after tuning values. Several algorithms reduce to tiny implementations (five lines for pagerank, 21 for Norvig’s speller).
