Neothesia is a free, open-source MIDI visualizer and piano learning application available for Windows, macOS, and Linux. Inspired by Synthesia, it transforms MIDI music files into colorful falling notes displayed above a virtual piano keyboard. The visual representation helps users identify which keys to press and understand the timing of musical passages. Players can follow animated notes to practice songs without relying exclusively on traditional sheet music. The application supports MIDI input, allowing compatible digital keyboards to interact with its piano visualization. Its GPU-accelerated graphics provide smooth animations and responsive visual feedback. Built with Rust and wgpu, it offers a cross-platform alternative to proprietary piano visualization software. Neothesia is useful for piano students, MIDI enthusiasts, and musicians exploring visual learning methods.
