Of course you need MusicTEX . MusicTEX consists of several TEX macro files and meta font files with music font definitions. The complete package is available on several bulletin boards and FTP sites. Recently I downloaded version 4.57 from rsovax.ups.circe.fr (in the directory /TeX/musictex). You need to acquire some knowledge about MusicTEX if you want to edit the source code after the translation process.
Further you need TEX. At the moment several good public domain packages are available. For the PC EMTEX is a good one. On the Atari ST I use TEX 3.1 by Christoph Strunk which I find pleasant to work with. These packages are also available at FTP sites, PD services or bulletin boards.
Last but not least use of this program is only of any use if you are working with MIDI files. A MIDI file contains musical information and is a standardized file format which enables to exchange music pieces between different software packages. Although many MIDI sequencer software packages have their own file format, most of them also support standard MIDI files.
This manual assumes that you have some knowledge of TEX and MusicTEX . If you are puzzled by any of the explanations in this manual see if reading the manuals of these packages can help you out.
