CCARH has created several data formats for music processing. The following schematic shows their relationship to each other and to other data formats which can be derived from the CCARH file formats.

1 Primary formats

MuseData "Stage 1"
This is the initial step in creating full MuseData files. Most notational aspects of the music are missing, since the data is typically generated directly from MIDI keyboard data entry. This format contains the pitch and a tick-based description of the rhythm, along with barlines. Each part is in a separate file, and if a part contains multiple time signatures, the music for a part will be broken into separate files for each time signature.
MuseData "Stage 2"
Also called an "S-file" (Source file). This is the primary symbolic form of the musical data. It adds symbolic descriptions of graphical elements of notation, such as which direction the stem of a note is pointing, what shape is the notehead on each note, slurs and dynamics.
I-File
"Intermediate File" which is a graphical layout of the music in a data format quite different than for MuseData files. The music is positions in a continuous single-system form.
Music PaGe (MPG) File
A variant of the I-file which breaks the continous system into lines of music. Each MPG file contains the content of a single page of music.
Compressed FormaT (CFT) File
CFT files are a compressed form of multiple MPG files representing a complete movement, work, or collection of works.

2 Data formats which can be derived from CCARH data files

MIDI files
Output format for listening to the music on a digital synthesizer.
Humdrum files
Output format for music analysis in the Humdrum Toolkit
SCORE files
Output format which is similar in scope to a Music PaGe (MPG) file for use in the SCORE program.
MusicXML files
Output format for import into other music processing programs such as MuseScore, Finale and Sibelius.
TIFF files
TIFF files are output of graphical music typesetting as a bitmap.
PostScript files
Similar visual display as TIFF output, but contains music in a bitmapped font for more flexible post-processing.

Both TIFF and PostScript files can be converted into PDF files.
