Morse MIDI

This Python package encodes a string input to Morse code and then converts it to a melodic MIDI file using a minor scale with randomized melodies.

Features

• Converts text to Morse code
• Generates melodic MIDI files from Morse code using a natural minor scale
• Randomized melody for each input, making each generation unique
• Default tempo of 180 BPM for a more upbeat sound
• Customizable tempo and base pitch

Installation

You can install this package using pip:

pip install morse_midi

For local development, you can install it in editable mode:

pip install -e .

Usage

Here's a simple example of how to use the package:

from morse_midi import string_to_morse_midi

input_string = "Hello World"
output_file = "hello_world.mid"

morse_code, word_count = string_to_morse_midi(input_string, output_file)

This will create a MIDI file named "hello_world.mid" in your current directory, containing a melodic representation of the Morse code for "Hello World" using a randomized melody in a minor scale.

You can also customize the tempo and base pitch:

morse_code, word_count = string_to_morse_midi(
    "SOS This is a test",
    "sos_test.mid",
    tempo=200,
    base_pitch=72
)

Melodic Pattern

The MIDI output uses the following characteristics:

• Uses a natural minor scale for a more somber sound
• Generates a random melody for each word, making each output unique
• Dots are represented by short notes
• Dashes are represented by longer notes
• Each word starts a new random melody
• Dashes are played as a perfect fifth above the corresponding dot pitch
• Default tempo is set to 180 BPM for a more upbeat sound

Dependencies

This package requires the midiutil library, which will be automatically installed when you install this package using pip.
