Developing Music Systems on the JVM with Pink and Score
summary
Pink and Score are Clojure libraries that run on the JVM: Pink: audio engine on JVM builds single‑threaded, block‑based (default 64‑sample) audio graphs with audio functions, control functions and a lock‑free event queue; demos show MIDI keyboard instruments, FM/additive/subtractive patches, ping‑pong delay and a graceful note‑off using a dynamic done flag so removals don’t click. Score is a data‑first note model that maps lists of events (priority‑queued, duration handled outside the engine) to interchangeable instruments: Score: data-first musical notation.
