SYNOPSISabc2abc file [ -s ] [ -n ] [ -b ] [ -r ] [ -e ] [ -t semitones ] [ -nda
] [ -u ] [ -d ] [ -v ] [ -Vvoice number] [-Pvoice number] [-nokeys] [
-nokeyf] [ -usekey(sharps/flats)] [ -OCC ]
DESCRIPTIONabc2abc 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 deco‐
rations (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[,Y...]
For multivoiced abc files (i.e. contains V: field commands),
only voices X[,Y,...] are copied.
-P X,[,Y...]
For multivoiced abc files (i.e. contains V: field commands), all
voices except X[,Y...] remain the same. Voices X,Y... are modi‐
fied according the other runtime parameters.
-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.
