DESCRIPTION¶
abc2abc is a simple abc checker/re-formatter/transposer. It will check
whether the
file given on the command line obeys basic abc syntax.
If you want to check an abc tune, it is recommended that you use
abc2midi
with the
-c option. This performs extra checks that
abc2abc does
not do.
The output of
abc2abc goes to standard output. Use redirection to save it
to a file.
OPTIONS¶
- -s
- Rework spacing in the file (which affects how notes are
beamed together when the music is printed out). This option does not
appear to be working correctly.
- -n X
- Reformats the abc file with line breaks every X
bars.
- -b
- Don't do bar checking.
- -r
- Don't do repeat checking.
- -e
- Don't report errors.
- -t n
- Transpose tune by n semitones. This function will
also work with K: none or one of -nokeys or -nokeyf. If a voice is
assigned to channel 10 (drum channel) using a %%MIDI channel 10 command,
then this voice is never transposed.
- -nda
- Convert double accidentals in guitar chord to another chord
though strictly not correct.
- -u
- Update notation; the older notation + + for chords
is replaced by [] and s s for slurs is replaced by
().
- -OCC
- Accept the old notation for chord. Normally this is turned
off, since it conflicts with abc draft standard version 2.0 for
decorations (eg. +crescendo(+).
- -d
- Re-notate the tune with all note lengths doubled. The unit
length specified by the L: field command is halved (e.g. L:1/8 to
L:1/16).
- -v
- Re-notate the tune with all note lengths halved. The unit
length specified by the L: field command is doubled (e.g. L:1/8 to
L:1/4).
- -ver
- Prints version number and exits.
- -V X
- For multivoiced abc files (i.e. contains V: field
commands), only voice X is copied.
- -X n
- For a file containing many tunes, the X: reference numbers
are renumbered sequentially starting from number n.
- -nokeys
- No key signature will be assumed. Instead, sharps and
naturals will be placed wherever they are needed.
- -nokeyf
- No key signature will be assumed. Instead, flats and
naturals will be placed wherever they are needed.
- -usekey sf
- This will force abc2abc to output the notes in the key
signature keys[sf] where sf specifies the number of flats (-negative) or
sharps (+positive) in the key signature. It is a number between -5 and +5
inclusive.
* Normally abc2abc will convert the deprecated notation for decorations (eg.
!ppp!) to the abc version 2.0 draft standard (eg. +ppp+). If you do not wish
to change to this standard include the -OCC flag.
