Looking at Music, an experiment with Kotlin, JavaFX, MIDI, and Virtual Threads
summary
A practical build using Kotlin, JavaFX, KT-Media, FXGL, Vaadin and GitHub Actions produces the MelodyMatrix app that records, visualizes, and replays MIDI as charts, fireworks and LED output; playback uses Virtual Threads to schedule thousands of tiny tasks and demonstrably plays back 4,000 MIDI events without glitch. The project includes a web storefront, an installer via JDeploy, screen-to-MP4 export, and a serial-driven LED strip demo — all working end-to-end.
