This repository contains sound libraries for use with react-native-soundfont. It is based on midi-js-soundfonts, but modified for use with mobile - mainly, a flattened directory structure with lowercase, underscored, filenames to obey Android's resource naming requirements.
To use a library with react-native-soundfont (Android), copy the mp3 files within the /sounds folder directly into android/app/src/main/res/raw.
Instrument names can be found in the names.json.
