abcMIDI is an open source graphical software written in Tcl/Tk that consists of programs for turning ABC music files into MIDI files, and vice versa. It requires a postscript viewer and a midi player. The software will typeset the files as PostScript files, and manipulate them in several ways.
Comprises of several command-line tools
The following tools are part of part of the abcMIDI project: abc2abc, abc2midi, abcmatch, midi2abc, midicopy and yaps. As you might have guessed, abc2midi is the tool that allows you to convert ABC files to MIDI files.
Furthermore, the abc2abc tool will help you convert ABC files to ABC files, but with different parameters, the midi2abc lets you convert MIDI files to ABC ones, and midicopy is a tool that allows you to copy parts of a MIDI file and output it with different parameters.
Last but not least, the yaps tool allows users to convert an ABC file to a PostScript (PS) file, and the abcmatch utility allows you to search for specific sequences of notes in ABC files that include several tracks.
