Neothesia is a cross-platform MIDI visualizer built in Rust that displays notes from MIDI files as colorful falling blocks on a virtual piano, similar to Synthesia. It helps people learn to play piano by following along with their favorite songs, either with an integrated synthesizer or a connected MIDI keyboard.

Use cases

  • visualize midi files as falling piano notes
  • learn to play piano songs with falling block visualizer
  • open source synthesia alternative for linux windows mac
  • practice piano with a midi keyboard connected to the app
  • render piano tutorial videos from midi files
  • play along with songs using an integrated synthesizer

When to choose

  • you want a free, open-source Synthesia alternative on Linux, Windows, or macOS
  • you want to learn piano pieces by following falling-note visuals
  • you want to connect a MIDI keyboard and practice interactively
  • you want GPU-accelerated, flashy MIDI visualization built with wgpu

When to avoid

  • you need sheet-music-based piano training rather than falling notes
  • you need a mobile (Android/iOS) piano learning app
  • you need a full piano curriculum with lessons and progress tracking
  • you need a lightweight MIDI player without visualization
