Tools for Generating and Working with MIDI Files
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 freely available under the
Creative Commons Attribution 4.0 International License.
If you're looking for a Rust library to generate and work with MIDI files, check out
libatm project, on which this tool relies. For

All datasets generated by All the Music, LLC have been released in the public domain, which means they are free for anyone to use for any purpose without restriction under copyright law. However, if we released the code into the public domain under CC0, we would have no control over entities using it with malicious intent.

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
gen single directive:
atm gen single 'C:4,D:4,E:4,F:4,G:4,A:4,B:4,C:5' test.mid
To brute-force generate a range of melodies from a set of notes and with a given length, use one of the
gen * directive.
The example below will output the melodies to a Gzip-compressed Tar file, with a directory structure that guarantees no more
than 4,096 files per directory.
atm gen tar-gz -p 2 'C:4,D:4,E:4,F:4,G:4,A:4,B:4,C:5' 8 C4_D4_E4_F4_G4_A4_B4_C5.tar
After generating a range of melodies with one of the
gen * directives (beside
gen single), use the
to determine which directory a particular melody was written to.
atm partition -p 2 'C:4,C:4,C:4,C:4,C:4,C:4,C:4,C:5'
