py_midicsv 1.10.0

A library for converting MIDI files from and to CSV format

py_midicsv

A Python library inspired by the midicsv tool (originally found here).

Disclaimer

This library is currently in Beta. This means that the interface might change and that the encoding scheme is not yet finalised. Expect slight inconsistencies.

Installation

py_midicsv is available from PyPI, so you can install via pip:

$ pip install py_midicsv

Usage

import py_midicsv

# Load the MIDI file and parse it into CSV format
csv_string = py_midicsv.midi_to_csv("example.mid")

# Parse the CSV output of the previous command back into a MIDI file
midi_object = py_midicsv.csv_to_midi(csv_string)

# Save the parsed MIDI file to disk
with open("example_converted.mid", "wb") as output_file:
    midi_writer = py_midicsv.FileWriter(output_file)
    midi_writer.write(midi_object)

Differences

This library adheres as much as possible to how the original library works, however generated files are not guaranteed to be entirely identical when compared bit-by-bit.
This is mostly due to the handling of meta-event data, especially lyric events, since the encoding scheme has changed. The original library did not encode some of the characters in the Latin-1 set, while this version does.
