abcMIDI is a package of programs written in C for handling abc music notation files. The software was created by James Allwright in the early 1990 and presently maintained by Seymour Shlien. It initially included the following programs:
- abc2midi for converting an abc file to a midi file,
- abc2abc for transposing abc notation to another key signature,
- midi2abc for creating an abc file from a midi file,
- yaps for producing a PostScript file displaying the abc file in common music notation and,
- mftext for creating a text representation of a midi file.
Seymour added two more programs:
- abcmatch for finding common elements in a collection of abc tunes and,
- midicopy for copying parts of a midi file to a new midi file.
Yaps has been superceded by Jef Moine abcm2ps and abc2svg programs. Midi2abc has been expanded to include mftext and various other features for supporting the runabc application. Abc2midi has numerous new features that are described in its own web page abc2midi guide.
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 web page.
