MIDI Player

MIDI Player (probably needs some better name) is a "beautiful" MIDI renderer. It's free and open source (BSD 2-Clause license).

The app is still in development. It probably contains many dumb bugs and is definitely not fully functional.

Features

• Input/output from/to .mid files and MIDI devices
• Rendering:
  • Raw frames for now, needs ffmpeg to actually turn into a video - see example script
  • No sound on videos
  • Only RGBA 1920x1080 60 fps is supported
• Configuration, with "hot reload" support
• Various customization options:
  • Background (single color or image)
  • Tiles (also depending on channel or index)
  • Particles
  • And more...
  • Styles can be changed at specific timings or various conditions
• Marking timestamps that you can use for configuration
• WIP: Inserting custom events (so that you can make e.g. subtitles)
  • Only TextEvents are supported

Only Linux is supported as the target platform for now. There is no GUI configuration for now. I plan to make a simple Qt-based configurator in the future.

Things that I (want to) work on

• Other platforms than Linux
• Customization of video format (framerate, resolution,...)
• Event triggers (so you can change styling when e.g a piano key is pressed)

Building / Installing

There are no binary distributions for now as I find the "basic" version not finished; you will need to build it from source.

See build instructions for more details.

Setting up

The two sources can be used for setting up the app:

• command line (see midiplayer --help for up-to-date help)
• config files (see documentation).
