A dependency-free, browser-native FL Studio and Ableton Live project visualizer, MIDI exporter, and MP4 renderer. Drop an .flp or gzip-compressed .als, optionally add your finished audio, customize the piano-roll visualization, and export a video without uploading your music to a server.
The production site is hosted at rollplay.cc. The application is static and can also be deployed by publishing index.html, styles.css, and the src/ directory, or by running the included Node server. The development server sets cross-origin isolation headers suitable for modern browser media APIs.
