How to

piano_visualizer was built with the intent to for it to be simple to use. You can render a piano video with simply 4 lines of code!

There are 2 main classes: Piano and Video Piano takes care of the piano rendering and the midi file parsing Video takes care of video management (fps, resolution) and exporting

INSTALL pip install piano_visualizer

Working in example.py

# Import the library after you have installed it
import piano_visualizer

# Create a piano with a midi file(s)
piano = piano_visualizer.Piano(["/path/to/your/midi/file.mid"])

# Create a video with resolution/fps
video = piano_visualizer.Video((1920, 1080), 30)

# Add piano to video
video.add_piano(piano)

# Export video on multiple cores (1 for single)
video.export("your/export/path.mp4", num_cores=6)

# You can add music too! (although it is sometimes offset from video)
# video.export("your/export/path.mp4", num_cores=6, music=True)

# Progress bars should show up
# Once your video is exported it will be at the path you specified!
