A small C++/OpenGL desktop application that renders MIDI files as animated visualizations. It supports live MIDI device input, configurable display settings, and exporting images or videos of the visualization.
Use cases
- visualize a midi file as an animation
- render a midi track to a video
- export midi visualization as png frames
- show live midi input from a keyboard
- create piano-style visualizations for music videos
When to choose
- you need to turn MIDI files into videos or images for content creation
- you want a lightweight, ready-to-run visualizer on Windows, macOS, or Linux
- you need live MIDI device visualization or command-line batch export
When to avoid
- you need to play audio alongside the visualization, as it does not render sound
- you need a web-based or embeddable visualization library rather than a standalone app
- you need DAW-style MIDI editing
