Batch MIDI Information

A tool to get quick MIDI information about a bunch of MIDI files, and save it to a JSON file.

Purpose

This was created for getting the info from all of my MIDIs into a single file for my website. My website works off an object which follows a similar structure to the structure in the midis folder.

The program looks for all .mid files in the midis folder, and parses through all of them. It calculates:

• File Size
• Track Count
• PPQN
• Note Count

and saves it into a JSON file with the following structure:

{
    "midiName": {
        "versionName": {
            "FileSize": string,
            "Tracks": int,
            "PPQN": int,
            "Notes": int
        },
        [...]
    }
    [...]
}

Usage

To use this project, follow the steps below

1. Clone the repo
2. Install Go
3. Put your MIDIs in the "midis" folder. Note: Use the structure prescribed in the README there.
4. Execute go run . to run the program
5. The info will be spit out as "midi_info.json" in the root directory.

Caveats

The code currently does not read note count accurately. I am working to solve this issue and get a more reliable note count but it may take me some time. If you are someone who has experience with note counts and want to help out, please make a pull request!
