Acknowledgments

We thank Anna Plaksin (@annplaksin) for her on-going contributions to mei-friend’s development via an NFDI4Culture 2023 research tooling development grant: Musicological mark-up with mei-friend.

We thank Matthäus Pescoller (@mapscl) for contributing to the documentation, and for his extensive testing of mei-friend in the creation of orchestral score encodings in the purvue of Signature Sound Vienna.

We thank the MEI community for input to the development of mei-friend. In particular, we would like to acknowledge Laurent Pugin (@lpugin), who contributed the code for schema validation, and Thomas Weber (@th-we), who helped to improve the speed mode module.

Components

The mei-friend Web application uses CodeMirror as its text editor, and Verovio as its music engraving engine. GitHub integration is provided using jsgit, jsgit-browser, and the GitHub REST API. XML-DOM manipulations are performed using tXml by Tobias Nickel. The MEI validation and RNG loading code is adapted from the implementation in the Verovio editor, kindly contributed by Laurent Pugin. It makes use of libxml2. PDF functionalities are provided by PDFKit by Devon Govett, using SVG-to-PDFKit. MIDI playback is implemented using html-midi-player. This is itself powered by Magenta.js, which also provides the SGM_Plus sound font used to sonify your encoding. Icons are taken from GitHub’s Octicons repository.

The mei-friend documentation website adapts the Docsy Jekyll template, which is based on the beautiful Docsy template for Hugo. The mei-friend documentation website is hosted by GitHub Pages.
