NAME

       abc2abc - a simple abc checker/re-formatter/transposer

SYNOPSIS

       abc2abc  file [ -s ] [ -n ] [ -b ] [ -r ] [ -e ] [ -t semitones ] [ -nda ] [ -u ] [ -d ] [
       -v ] [ -Vvoice number] [-Pvoice number]  [-nokeys]  [  -nokeyf]  [  -usekey(sharps/flats)]
       [-useclef(treble/clef)] [ -OCC ]

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.

       -useclef
              This  works with only the -t (transpose) and provided the abc file does not already
              have a clef command in the K: field. It does not support voices.

       * 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.
