This information is made available at www.openmidi.com or in this repository for public use.

The MIDI data for each device is saved in yaml files.

The yaml files are organized in folders data > brands

Each yaml file follows a template (see template below)

After a new yaml file is created, the mapping.json file needs to be updated to map the brand and product name to the new file.
