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[,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 modified according the other runtime parameters.

       -X n   For  a  file  containing many tunes, the X: reference numbers are renumbered sequentially starting
              from number n.

       -xref n
              Only the tune with X: n is processed.

       -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.
