### abcMIDI package
abcMIDI is a package of programs written in C for handling [abc music notation](http://abcnotation.com/) files. The software was created by James Allwright in the early 1990 and presently maintained by Seymour Shlien. It initially included the following programs:
1. abc2midi for converting an abc file to a midi file,
2. abc2abc for transposing abc notation to another key signature,
3. midi2abc for creating an abc file from a midi file,
4. yaps for producing a PostScript file displaying the abc file in common music notation and,
5. mftext for creating a text representation of a midi file.
Seymour added two more programs:
1. abcmatch for finding common elements in a collection of abc tunes and,
2. midicopy for copying parts of a midi file to a new midi file.
Yaps has been superceded by [Jef Moine](http://moinejf.free.fr/) abcm2ps and abc2svg programs. Midi2abc has been expanded to include mftext and various other features for supporting the [runabc](https://ifdo.ca/~seymour/runabc/top.html) application. Abc2midi has numerous new features that are described in its own web page [abc2midi guide](https://ifdo.ca/~seymour/runabc/abcguide/abc2midi_guide.html).
Components of the abcMIDI package are parts of numerous applications for creating and editing abc files. Compilations of these components for various operating systems can be found on [The ABC Plus Project](http://abcplus.sourceforge.net/) web page.
