atm-cli is a command line tool for generating and working with MIDI files. It was purpose-built for All the Music, LLC to assist in its mission to enable musicians to make all of their music without the fear of frivolous copyright lawsuits. All code is released into the public domain via the Creative Commons Attribute 4.0 International License. If you're looking for a Rust library to generate and work with MIDI files, check out the libatm project, on which this tool relies. For more information on All the Music, check out allthemusic.info. For more detailed information about the code, check out the crate documentation here.

atm-cli is written in Rust, and thus requires the Rust toolchain to compile. Follow the instructions at https://www.rust-lang.org/tools/install to install the toolchain. Once that is complete, clone the repo and compile the tool:

$ git clone https://github.com/allthemusicllc/atm-cli.git
$ cd atm-cli
$ git submodule update --init
$ cargo build --release
$ cargo run --release -- -h # show usage

To generate a single MIDI file from a melody, use the single directive:

atm single -n 'C:4,D:4,E:4,F:4,G:4,A:4,B:4,C:5' -t test.mid

To brute-force a range of melodies with a given length, generated from a given input note sequence, use the batch directive:

atm batch -n 'C:4,D:4,E:4,F:4,G:4,A:4,B:4,C:5' -L 8 -b 20 -p 2 -t C4_D4_E4_F4_G4_A4_B4_C5.tar

After brute-force generating a range of melodies with the batch command, lookup the output batch for note sequence with the partition directive:

atm partition -n 'C:4,C:4,C:4,C:4,C:4,C:4,C:4,C:5' -p 2

You can download an existing dataset containing all 10-note melodies containing the 8 major keys in the Middle C octave from:
