Tone.js MIDI Generator

This project utilizes OpenAI's GPT-3.5 model to generate MIDI scores in JSON notation that can be played back using Tone.js. The generated JSON music score includes tracks with labeled notes containing pitch, duration, and startTime. The duration and startTime are represented as numerical integers.

2. Setup:

   • Clone this repository to your local machine.
   • Open the index.html file in a web browser.

3. Interface:

   • The interface allows you to adjust between direct generation and code generation of MIDI music.
   • Use the slider to select between direct generation and code generation.
   • Click the "Start Generation" button to initiate the MIDI generation process.

4. Playback:

   • After initiating the generation process, the generated MIDI music will be played back automatically.
   • The playback can be controlled using the play/pause toggle button.

Code Overview:

• JavaScript (main.js):

  • The generateCode function uses OpenAI's API to generate JavaScript code for MIDI music generation based on predefined prompts.
  • The generateMidiJson function generates MIDI music directly by calling OpenAI's API with specified prompts.
  • The loadJson function loads the generated MIDI JSON based on user selection.
  • The startPlayback function starts the playback of the generated MIDI music using Tone.js.

• HTML (index.html):

  • Provides the user interface for controlling MIDI generation and playback.
  • Includes necessary scripts for Tone.js and MIDI playback.

Usage Notes:

• Ensure you have a stable internet connection to utilize the OpenAI API for MIDI generation.
• Adjust the slider between direct generation and code generation to explore different approaches to MIDI music creation.
